Recently I have updated my Windows to 8.1 (from 8.0) and after that I have encountered that Youtrack is empty. I have found that Youtrack stored its files on the following path C:\Windows\System32\config\systemprofile\teamsysdata in the old OS. Windows update created new folder for the new OS version and old one was marked as ".old". Obviously that all previous youtrack files stayed in the Windows.old\Windows\System32\config\systemprofile\teamsysdata. When youtrack didn't found any files it creates new folder (on the path C:\teamsysdata) and creates all settings here from scratch. I tried to copy old files into the new folder but it doesn't work. Webserver throws exception HTTP 500.
Could you please say how I can restore youtrack projects with using of old raw youtrack files?
I would be very appreciate for help. Thank you in advance!
