XBMC on Windows 7 64 bits not responding.

Hello,

I just installed XBMC 12.1 for Windows on my Windows 7 Home Premium 64 bits.

The first time I did run it, I was able to choose movie and picture folders, suddenly when I did try to choose music folder then XBMC stop responding.

Now, every time after open XBMC it stops responding.

And I unable to close the application or process on Task Manager.

How to solve this issue, please?

Thanks in advance.
