Upgraded to Windows 7, cant run anymore

[Elias_Maluco]

Hello all.

I have been playing KB: AP a lot, love it.

But recently I gave my PC a major upgrade, changed almost everything. Then, I backed up my files, formated my HDs, and reinstalled everything. And this time, I decided to finally go with Windows 7.

Unfortunately, I found that I cant run KB: AP anymore. I re-downloaded it from Gamersgate, installed it, applied the gift pack. Then I try to run, activation screen pops up, I activated it using my serial. Then nothing.

Try again. Mouse cursor changes to hourglass, disk activity can be heard, then.. nothing. Cursor goes back to arrow, no error messages, literally nothing. Happens everytime I try it. Tried running in XP compatibility mode: nothing. Tried running as admin: nothing.

I already have some other games installed(namely: Stalker: Cry of Prypat, Anno 1404, Gothic 3 and Portal). All running fine. No crashes at all so far.

My system:

AMD Phenon II 3.4mhz CPU
2x2gb RAM DDR 1333 (g-skill)
ASUS M4A785TD-V EVO motherboard
ATI Radeon 5770
Windows 7 Ultimate

The video-card I already had prior to this upgrade, everything else is new. I was playing AP with this same video card in my old config (with Windows xp), and it was working fine.

I do know AP is reported to work fine in Windows 7, so its something on my config. But what? Fact there is no error messages makes pretty hard to locate whats wrong. What can be happening? How can I find out whats making the game fail?

Any help will be much appreciated.
