Arma2 suddenly not starting anymore - weird problem

[jnx 10]

Lo folks! I'm very confused. I've been happily playing and editing arma ever since eu release. Now suddenly the game doesn't start anymore. When I try to run it, dvd drive goes wroomwroom for a second and then nothing. No error messages or anything. It just doesn't start. I tried reinstalling but still the same thing.

There were no changes in my comp or software before the issue except for Comodo firewall upgrading itself. However the game doesn't launch even when comodo is shutdown.

Any ideas or similar experiences?

stuff:

Asus p5k

intel core2duo e6550

3 gb of ram @800mhz

HD4870 1gb pci-e

Windows 7rc build 7100

Only idea I have is that the win7 would've had a hidden update somehow messing arma2 up. Other games don't have problems tho :/

Can't anyone say anything about this?

might be a firmware issue with your DVD drive. See if you can update the firmware from the manufacturer
