Problem with GP4.gamer.nl

Hello everyone.

I've installed the GP4.gamer.nl Seasons 2003 and 2004 via CSM and they both crash when I try to run the game.

Season 2003 works a bit (i.e. the race is starting) but at a random moment within 2-3 minutes I get a message saying that the game has stopped working.

Season 2004 (both Normal and High Res. versions) crash when the race is loading.

Every other mod I am using with CSM works fine, so I think there must be something wrong with these specific mods.

Any ideas or help?

Thanks a lot in advance

Thomas
