Left 4 Dead Won't Run With Windows 7 Home on Mac *help*

Hey everybody, I have a little problem here.

Today I just installed windows 7 home premium on my macbook pro, the install went smoothly and I got everything running well. I installed all the drivers for the mac from the mac OS X cd once windows 7 was installed so that the sound and everything else works. I then installed Left 4 Dead and steam and signed in on my steam account. Left 4 Dead updated, then I tried running it only for it to never open.. When I click launch it just says that it's loading, then the little box goes away, and nothing happens. I even tried loading it using admin and using XP and Vista emulations both with service pack 2 and 3. I know I definitely meet the minimum requirements for the game (brand new fully loaded macbook pro) so I'm not getting why the game won't run? Does it have to do with windows 7 or that i'm running it through sandbox on a mac? Although everyone says they are running it just fine. Any help would be greatly appreciated!

Have you tried compatability mode?

@gilbo : he tried. He just told so.
Have you tried to delete the game and redownload it?

I haven't tried uninstalling/reinstalling it, I'll do that now and let you know if it works. I have it on disk but the updates were downloaded so I'll just try deleting everything and reinstalling by downloading it instead of from the disk.

I didn't realise he meant that by 'emulation' sorry....

It didn't work. Once again it said it was preparing to launch with the little box and the screen went black for a second then just back to the normal windows background. Same as last time. Any ideas?

Can it be something having to do with my video card? I don't know if it needs and update or something but while trying to get a screen saver running in the control panel all it says is "the screen saver can't run because it requires a newer video card or one that's compatible with Direct3D". Is there anyway to check all these settings to make sure everything's running ok?

right click the game in steam and defrag the game in there then reboot windows and open steam again to see if there are anymore updates just let it sit for a few minutes then try to run the game again.

I can't find anything about defraging the game when I right click. When I go to the properties of the game it says there is 0% fragmentation. I've tried restarting and all that several times.

Sorry! Have you tried a PC? Games arn't paticullarly Mac friendly.
