Cancel: Calibre just... disappears!

[ZaZg]

Sorry, cancel this ticket. I created an empty folder for my books and now it works...


Hello,

I've just installed Calibre on my Windows Vista machine. The installation went smoothly, but when I try to run it, it just goes away...

Everytime I start the program, it displays the message
"calibre's book storage format has changed [...]".
Then, I can see it tries to draw a screen, but then it simply disappears. No trace of any process in Task Manager, either.

Any help would be greatly appreciated. I was using libprs500 until now, and was really enjoying it. I just can't wait to try the new features on Calibre.

Thanks you for your great work.
