Calibre is Already Running message

mommylego · 04-09-2013, 10:44 PM

I've been using Calibre with no problems for several years and all of a sudden tonight when I try to open it I get the message saying "Calibre is already running. Calibre may be running in the system tray, in the upper right region of the screen." I am running Mountain Lion on a MacBook Pro and I tried deleting the GUI lock file from terminal, but I get a message saying the file doesn't exist. I don't know how to get the error message output to post here, but can try if you can tell me how to do it. Thanks so much for any help you can give!

Just reboot your computer.

That was the first thing I tried and it didn't work. I finally tried disabling the antivirus software and rebooting the computer and it is working again. Yay! Thanks for the help.
