Help! running LR 4.3 on Win 7 Pro, 3 gigs ram, Service Pac 1, everything up to date. LR 4.3 seemed to fix constant hang ups in LR4...until recently. I am now plagued with "LR has experienced a problem reading from cache and needs to shut down" - typically while in "develop" working on pics.

this is happening with every use and is driving me INSANE! Any ideas/help appreciated.

The cache might be corrupt and need to be cleared, or you might have a disk problem causing more than a few corrupt files.

so that would mean deleting this entire file?

users\ \ \ \lightroom\lightroom4 catalogpreviews.lrdata

there are 16 separate folders, along with 2 files "root pixels" and "previews"

Yes, I would delete all the preview folders, plus the previews.db and rootpixels.db files, AND clear the acr cache. After that you can rebuild all your previews and usually the problems have gone. Do it overnight if you have a lot of files.

thanks guys....it did not work! Deleted all preview folders, and 2x files noted, along with acr cache. Back to the same problem with the "preview cache" crash.
all folders are on the same directory as the install.

I can only note that obviously this is bug that Adobe needs to work on - all the users that are complaining about this same problem is just crazy and can't be attributed to disk problems.

any other ideas or suggestions greatly appreciated.

Have you tried deleting your Preferences file? That sometimes seems to get corrupted and cause funny things to happen. This problem of yours isn't normal!
