mx sim keeps crashing

[Stewart#642]

this is getting really annoying. basically after every 2 (full) races I do, the game just crashes. I have an ATI 5650 graphics card, and iv'e tried about everything. Iv'e disabled Catalyst A.I.
in the problem details it says:

Make sure you have the latest drivers from ATI. Their driver download page is here. They've had some really bad memory leaks in the past which will cause problems after a few races.

I updated the driver, but it still crashes after 2 full races.

Now it cant even do 1 race without crashing :/ this is real annoying

Does it happen on a specific track? Does it still happen if you turn off demo recording?

[Stewart#642]

it happens on every track, I turned demo recording off, sadly it didn't work

Give this a try: http://support.microsoft.com/kb/929833

You might want to try renaming or deleting your config file too. (From the Windows Start menu, open All Programs / MX Simulator / MX Simulator Personal Folder. Delete the file named "config".)

thanks for your help, but still it doesn't work

Reinstalling Windows might help.
