Blitzkrieg Patch Problem

[Riandus]

Ok, i have the first game of Blitzkrieg, no expansions.

I wanted to play online but because idont have all those maps its pretty hard to find a game, so i found out that i had to download a patch.

from filefront i downloaded this patch: bkpatch1_2.zip - FileFront.com
It was given on the site of blitzkrieg.de

Installed it, but then the problems start.

When i want to play this game, it says Wrong disc inserted. I have no idea what could be the problem. But i didnt have this problem before i installed the patch.

I have this game running on Vista

Now I'm hoping if you guys know the solution.
