I recently got my hands on Lock-on modern combat, without the expansion that is. I installed it, no problem there, but whenever i launch the exe file, i just hear this "plane sound", and i see the icon in the start bar, however, it quickly closes the entire application again.. If i launch it from teh autorun, it will simply do the same thing, but relaunch the autorun afterwards - So it's leaving me at ground zero

My specs are as follows:

2ghz Duocore
2 gigs ram
around 1.5 gb free space (when installed)
G-force 7600 go.

I'm sure the newest Direct X has been installed, and i can't seem to think what more could be causing it ? I tried reinstalling like 3 times now, but same sh*t :S

Vista?
