Hi this is my first post and feel free to call me stupid or ridiculous but when I try to open Calibre it asks me to select a location for my ebook library which I do then nothing else happens and when I click on it again to try and restart it I get a message saying Cannot Start Calibre because Calibre is already running. It is running in task manager but no program comes up.
PLEASE HELP!
Thanks
P.S. I run Windows Vista
