few bugs after reinstall

ive just done a fresh install of the game and have encountered a few probs. firstly, there is a strange graphical glitch behind the helmets of both williams and mclaren cars, where you can see straight through to the driver body. secondly, as i'm running the patch version, i cant use carset creator. so i tried exporting helmets thru gp4master and they only show up at close range - at distance you can only see the old helmets.

any help appreciated, cheers!

I think the last problem is you need to downsample the helmet in gp4master.

The first problem, a screenshot would help!

cheers steven, the 1st bug has mysteriously disappeared, and the second one is solved!
