Media Pending on different clips every time I open project. Please help!

Hi,

I have an infuriating issue with Premiere Pro CS6 which started out of nowhere in early March and whatever I do, I cannot fix it.

I am running Production Premium CS6 on a custom built, 32GB RAM desktop PC with a Quadro K2000 Graphics card and Windows 10. I've used Premiere for years with no problems until early March when a client sent their short film for me to colour. The project loaded up fine in Premiere, I exported an xml, graded the project in Da Vinci Resolve then exported the individual clips as DNxHD files to be imported back int Premiere for the finishing touches as I have done hundreds of times with no issue.

In this instance, Premiere refused to import the folder of clips and would crash every time I tried to import it. I had to do a workaround whereby I exported the project as a single clip from Resolve and put the cuts in manually. I thought this was a one off but no, the next project, two weeks later did exactly the same only with the added frustration of not loading clips, seemingly at random every time I opened the project, leaving them as "media pending" with the clip names in the project bin in italics. When I tried to re-link them, Premiere crashed.

I figured I was just unlucky with two dodgy drives from clients but this week I started my own project, same workflow as always and STILL the issue persists. This is now starting to cost me money as I can't take on any jobs until it's fixed. This is an issue which has appeared out of nowhere and will not go away.

So far I've tried the following with no joy...

Uninstall/reinstall

Turn off GPU acceleration

Renaming folders

Creating new sequences/projects

unchecking the XMP options in preferences

Trashing prefs

Manually deleting cache

Deleting cache via the preferences

Deleting fastimporterMPEG file

Trying different project settings and presets

The clips are all DNxHD, all consistent frame rates etc, the same as I have always done and as I say, the issue just appeared overnight and is having a hugely detrimental effect on my business.

I wanted to call support but apparently I no longer have that option (!!?)

I paid almost a grand for the software, I don't want to move to CC, I just want what I have to work as it should.

Please someone help as this is driving me insane!
