LR only open once if I start my compuer. Then If I close LR I can't open it again until I reboot the computer. I tried signing out of CC App and then signing in again but still LR only starts to open and then nothing opens up. I tried renaming the LScache folder but there is no such folder in my program\commonfiles\adobe tree. I can open LR only after I reboot the computer.
If you have a Windows system, the answer may be in the following procedure.
For some reason Lightroom does not exit from memory and will not allow a restart, you would see multiple listings of Lightroom if you look in Task Manager when you cannot restart..
Try this fix-
If not working seek other answers.
Thanks. That fixed the problem.
