Medal of Honor: Airborne Forum

For some odd reason, the game says I've got ''0 MB of system memory'' even though I have 6 GB XD (So the game freezes up on launch) Here are my system specs:
ATi Radeon HD 3870, 6 GB of RAM, quad core CPU 2.5 GHz, latest drivers, windows Vista 64-bit
I've never had this problem before with any other game, and every other game I have can detect my RAM....I even tried ''Can You RUN it?'' to make sure the RAM is detectable and it says I completely pass minimum and recommended requirements. Like I said above, my drivers drivers are up-to-date (thanks Beast! :)) and I've got the latest version of windows Vista 64-bit. Is this game known to have this issue or does it not support windows vista 64-bit edition or somethin? I've noticed other people have had this problem but I don't think a solution has been found :(

Thanks for any help you guys can provide.

UPDATE: I got the game to launch without the system requirements check and it ran fine, but theres no sound now :( Grrrr...
