GUI problem, tried everything in the FAQ

[kiraa]

Hi there, i'm using windows vista SP1 and can't run the GUI of Calibre.
I tried the folowing things in the FAQ and wasn't able to suceed

There can be several causes for this:

* Any windows version: Try running it as Administrator (Right click on the icon ans select “Run as Administrator”)
* Any windows version: If this happens during an initial run of calibre, try deleting the folder you chose for your ebooks and restarting calibre.
* Windows Vista: If the folder C:\Users\Your User Name\AppData\Local\VirtualStore\Program Files\calibre exists, delete it. Uninstall calibre. Reboot. Re-install.
* Any windows version: Search your computer for a folder named _ipython. Delete it and try again.
* Any windows version: Try disabling any antivirus program you have running and see if that fixes it. Also try diabling any firewall software that prevents connections to the local computer.

So i made a debug.
Here it is :

Traceback (most recent call last):
File "debug.py", line 101, in <module>
File "debug.py", line 79, in main
File "C:\Program Files\calibre\library.zip\calibre\gui2\main.py", line 1520, i

Thanks for your help, sorry if my english is bad

Cant open database file means either you've chosen a bad location for your library or you have an antivirus program interfering
