Ok guys, I installed the game and it worked (not online, though). But i saw that i needed the patch to play online. So i installed the Service Pack 1 patch. Now when i click on the icon to start the game it says to INSERT WORMS WORLD PARTY. The CD is in. I have Vista. And suggestions?

try a Service Pack 1 for another region. various regions used different CD Protections on the game.

I just had the exact problem. The game was working fine, I installed my region's patch and now it is asking for the disk.

As franpa said, try another region, or you may not even need it. The copy I have comes with service pack 1 already.

Thank You it works
