Calibre won't open since updating
Hi, I updated Calibre to the latest version the day before yesterday. The first time I opened the program it worked fine, but since then I have been unable to open the program - when I double click on the icon, it says it is opening, but nothing happens. The computer doesn't crash etc, just nothing happens.
I tried re-installing the new version, and installing the old version, and in both cases I was able to use the program once, and then not again. I am using Mac OX10.5.8, any ideas?
