A fix to Lightroom's “Server Busy Error” on a Windows 7 64 bit computer:
I see in the discussion threads there are a LOT of frustrated people over this Server Busy issue, so I hope this helps someone. This is what Adobe tech support had me do, which fixed my problem. I got through on the phone right away, and the fix took no longer than 20 minutes to determine, with the support person remoting into my computer.
- I already had Lightroom 5.6 installed through my Creative Cloud subscription, and it had worked for a few weeks for me, although with increasing problems with the Server Busy box popping up. I was able to get rid of it by switching to Switch and Retry, but eventually it locked me out entirely.
- Tech Support told me the problem was a permissions issue.
- Try the following and see if it solves your problem:
- In C:\Program Files (x86)\Common Files\Adobe, find the SL Cache folder and move it to your Desktop.
- In C:\ProgramData\Adobe, find the SL Store folder and move it to your Desktop.
- R Click on your Lightroom icon and “Run as Administrator”.
- If it opens correctly, that shows it is working now.
- Close Lightroom and reopen the application normally.
At this point I was good to go again. 9/17/14

Yes, I have, on two separate occasions.
But, I can try it again...
