"Control socket is not connected" when starting TOR/Vidalia

I don't know why. But TOR/Vidalia just stopped working for me. I've never had any problem with it. Just installed and launched without any error messages.

Still, this message pops up: http://i.imgur.com/Jponv.jpg

"Vidalia was unable to authenticate to the Tor software. (Control socket is not connected).

Please check your control port authentication settings"

**?!?!?!?! **

Googled for it without any success. Reinstalled Vidalia/TOR x times, installed the latest version (Alpha), etc etc. Why won't it work anymore? I havent change any setting at all. Anywhere.

Version: vidalia-bundle-0.2.3.10-alpha-0.2.15-1.exe Windows XP

Please, help.

Thanks in advance, /K
