Hitman Blood Money Problem

[THE CHOPPER]

I've installed the game, it works but I can see through all the walls and stuff. They're semi transparent. I can't figure it out, I messed with the graphics settings in game but to no avail.I'm running the latest patch( I think ) The only thing I can think of is that maybe my AA or AF is conflicting somehow as these are set not to be application controlled through the ATi catalyst control centre. My system specs are:

Opteron 146 running 2.6 stock volts Processor
Asus A8n-sli motherboard
HIS Radeon X1800XT 512mb Graphics card
2 gig corsir value memory
Tagan TG480-U01 PSU

Reinstalling doesn't work and I know it isn't the disc as this is the second copy of the game I have tried. Help me out guys this game looks to be really good but I can't play it like this

Dunno like I had this problem when I had my old Radeon 9000. It was weird anytime someone signed into msn or kept messaging me all the walls were transparent like a wallhack of some sort, happened in online games too lol.

I did a bit of a search on the net and found the answer. I had to turn some shadow settings completely off within the game. Now I'm stuck on level 3 HAHA
