Arma won't start (launch)

[Nicolas Eymerich 0]

Okay. Yesterday evening, after 10 hour of hard work, I've bought my Arma copy. I've installed it but when I tried to launch, the application, after the copy protection check, was usally to reboot system.I've tried to unistall and reinstall again but nothing....

(Btw: I Had this problem even with the demo)

Those are my specs:

P IV Prescott, 3.4

2 Gb Ram

Ati 1950 X, 512 Mb (Catalyst 7.1)

and..

Sound blaster audigy 2zs platinum pro.

After I've tried to update any driver possible (the newest directx) I've tried to update the sound card's drivers.

Result? It worked.
