The instruction at 0x241e3b99 refrenced memory at 0x203f65c8 the meory could not be read.

Ok, so now I get this error everytime I start up the game it gets to the main screen then crashs me to this error.

This has to be 1 of the worst games to be released like this, I have tired everything. Direct x drivers vid card drivers, adding stuff to stuff. I read the"help" thread or whatever and it covers this bug but it won't fix it. This game has been nothing but problems.

Do I HAVE to have the singal player version installed for the muti player version to work or something? I had both before but I had to re install windows because the game bugged my comp so bad. So, the muti and singal playr version worked before but now I get an error on the muti player version.

Help if you can plz. thanks.

No, the games run seperately, they don't depend on each other.

Right-click on the game > properties > local files > "verify integrity" and "defragment".
Make sure Steam interface language is English.
Keep the ingame's settings for Video moderate, in any case lower than what you have in singleplayer version, and resolution 1024x768 or similar widescreen.
