Lightroom CC won't import images

I "fixed" it by deinstalling LR6 and reinstalling it....
Now it seems to work like before.... But I bet the problem is bigger considering the there are a lot of people with the same problem.

im having the same issues, i just did the latest CC update and now its all gone pete tong !!!

even pictures i viewed and worked on last evening it now says It cannot find. it wont let me reimport anything as it says there's nothing to import??

And the same for me....
It seems that images are randomly imported but most are not imported and LR gives the error as shown above.....

I tried deleting the files: /Users/[user name]/Library/Preferences/com.adobe.Lightroom5.plist and shut down my mac. after reboot it still doesnt import all files.....

And import seems slower than ever...

So, has this issue ever been fixed?  Imports worked, if I recall, directly after upgrading, but they do not work now!  I thought I was having memory card issues, but I get the same result when importing from a desktop folder.  I either get the file not read error shown below, or nothing as other have posted if I try the import again.  What the heck is going on ?????   I am on the current LR CC 2015 as of August 8, 2015.

Opened LR CC and converted existing CPVGolf-2.Ircat which is a Lightroom 5 catalog.  I'm running a Mac Mini with OS X 10.10.3

On Import, all 175 photos have been copied into the target folder ok but only 5 seem to be listed in the catalog, and even those are not readable:

The images are in such a state that no editing can be done on them in LR CC.

In another catalog I was able to see 9 out of 108 photos in grid view.  Only one of those 9 rendered OK in develop but still, the message at the top was:

All the other image are so pixelated they cannot be useful.

I deleted the preferences file Preferences

/Users/[user name]/Library/Preferences/com.adobe.Lightroom6.plist as someone suggested but with no effect.

As of this time LR CC is useless to me.  It would really be nice if Adobe had some email support or something.  I have put up with this problem for the 2 months since I first downloaded CC.  Right now, I always try to import images into the LR CC catalog and when that fails, I delete the images from the folder and the converted LR CC catalog and revert back to using LR 5 with the original LR 5 catalog.  In LR 5 I have absolutely no problem with viewing and editing all 175 of the previously mentioned images. 

Just looking for guidance.  What can I test next?

I have not been able to import files in Lightroom CC either.  I am shooting Canon 5DMK3 - .cr2 files.  I had two.mov movie files in the folder and when I removed them I was able to import the RAW files.  Adobe needs to take a serious look at this.  I usually download all the files off a card via LR - image and movie files - that way I can add custom metadata and keywording during import.  This will def be a PITA if I have to change my workflow to deal with images and movies separately even if just for import.

This is not working for me either. All the same issues as above. Working on a Mac.

I've tried all the usual stuff, deleted prefs, uninstalled, e.t.c.

I left it in import mode "Importing Files..." for over an hour and nothing imported. I've also tried just selecting 1 image and still the same issues.

I've copied all the images to my computer and I've also tried just moving the photos to the desired location and still nothing. Something is really wrong and it would be great to get a fix, this has been open for 6 days and seems it should be fixed by now.

Snice Adobe hasn't seen fit to answer in any meaningful way, I did the only thing I knew how. I uninstalled Lightroom (keeping my preferences/presets), and reinstalled it. Now it works. PITA, but successful.

I'm having the same exact issues as ddawg05. I recently upgraded to Lightroom 6, and since then I have not been able to import images. I get screens that look just like the ones ddwag05 uploaded. I have tried rebooting my Mac, I have tried rebooting Lightroom, and nothing is working. I do get to see the preview photos, but once I click "import," I don't see them again. I gave it quite a long time, thinking maybe Lightroom 6/CC just takes longer, but the progress bar isn't showing any movement. It just gets stuck in one place, about 1/4 of the way over from the left, and stops. Any suggestions would be helpful. I have the same things plugged into my USB ports that I always have plugged in. Why would there be a problem now after I have been using Lightroom for years? It sounds like there is a glitch in Lightroom, and the suggestions are Adobe's way of getting around the glitch. Is Adobe working on a permanent fix for this issue? And, by the way, EVERYTHING takes longer in Lightroom 6/CC. Very frustrating. You expect upgrades to improve software, not take it a step back.

Also, I did try all of your suggestions and they did not work. However, I was able to import the images with Adobe Bridge, so the problem is definitely with Lightroom.

I am also having a similar problem. Mine hangs before I get to even see the photo previews. Sometimes, I don't even get the import screen. I'm running the latest version of LR CC on a Windows 8.1 desktop. I've been experiencing this problem sporadically since I've upgraded from 5 to CC. I've tried importing from both SD card and a local folder on my desktop. I've rebooted. Sometimes that seems to work, sometimes not. Here is a screenshot of my library after trying to import (showing the photos from my previous import (it doesn't show, but the cursor is just a spinning circle).
