New Patch is causing loads problems

Today I tired to start up crossfire. But it had to download the new patch so I let it. After the new patch it had a memory read error. So I just thought it was because of the new patch. "Fine" Tried to restart CF same thing, everytime.

A) Its not my comp cause all of my drivers are updated including windows update.
B) I have been playing CF for almost a year now so its not a graphic issue.
C) Firewalls and antivirus are off
D) Cookies are empty

So what could the problem be. Hhhhhmmm. It could be the patch but if anyone knows anything could you let me know or post if you have similar probs.

OS: Vista HP
Mem: 500gb, 1gb ram
VD: ATI Xpress 200
