"Lightroom encountered and error when reading from its preview cache and needs to quit"

I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.

Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.

Your thoughts?

You need to delete the Preview Cache.

It is located in the same folder as the Lightroom Catalog. The preview cache name ends with Previews.LRDATA and should be deleted. Do not confuse this with *.LRCAT, which should not be deleted.

I have exactly the same problem. It started appearing when I moved my entire file structure to an external drive. However, the first seesion I used the files on the external drive, LR worked fine with no errors. In my second session, it also worked well for sometime, and then I started experiencing this error. Initially, I deleted the preview file as recommended on this forum. It would work for a while, then the error would appear again. Now, it appears almost regularly.

I am using Macbook Pro Retina display, LR5, external drive 1TB Toshiba. Any help/ideas greatly appreciated. Thanks.
