Every time I am invited to join a party with online friends the game just crashes, after I crash I cannot log back in until they remove me from the party

Noobish,

Have you tried doing an uninstall and reinstall of the game and see if it persists?

Noobish,

Reply back with the latest error log from the folder that Sixen mentioned.

Noobish,

Let's get some more information. Go to start->run->type 'msinfo32'->ok->expand "software environment"->running tasks->click on one of the running tasks->press 'ctrl a" to select all->then copy and paste that information to your reply.

Noobish,

Can you also post some information about your computer? You can find this information in the Direct X Diagnostic Tool:

Click on Start
Click on Run
Type in: dxdiag (In Vista, type dxdiag in the search field)
Hit Enter or OK

Click on the Save All Information button at the bottom, and create a dxdiag text file, and copy and paste the first half of the dxdiag file (down to the "Sound devices" section) into your reply.

Noobish,

Try installing the latest drivers for your video card and see if that has any effect:
