I have reinstalled LrC and this did not help. I have gone to my backup file from 2 days ago and opened it. LrC die open with that file. I then backed up my catalogue as I closed the LrC app. On attempting to relaunch fro the nornal shortcut I was presented with the original issue.
Is this a LrC issue or have I screwed sommeting up? any help would be appreciated.
I had similar issue, contacted support and it had to do with my LR catalog location. I moved from D: drive to my C:\User folder and LR opened.
Thanks Robert I'll give it a try. Although my catalog is already in my C: drive. I'll move it to D; and then see if the issue is still there. If it is stiil displaying the error I'll move it back.
I had to move it "from" D:\Lightroom "to" C:\Users\me\Docutments\LR_Catalog LR Support implied it had something to do with permissions, even though earlier versions of LR had no problems. But, moving there did work.
Problem Solved..... After trying many potential solutions that did not work, last night I tried restoring from a backup file that was 2 days older than the one I used when the problem first arose. This resolved the problem and LrC is now opening properly.
I dont know why this backup worked and the original one I used didn't. I just so plesed to be back to normal with he app.
