BF2 works but not PR or FH2

[Rawhide]

Hey, third thread in three days.

BF2 1.5 is done and updated and also working fine on highest settings.

Problem is that PR and FH2 doesn't start.

When I doubleclick FH2/PR the screen goes black and the whole computer freezes.

Windows 8 - Any tips or trix?

Can't find anything google worthy.

OK, update.

 FH2 works in Windowed mode but not Fullscreen.

My reaction is

O____O

Compatibility mode, run as administrator, unblock from firewall, many suggestions. What have you tried already?

Compability, Windows XP Service Pack 3, running as admin, Firewall check, all working in windowed mode.

Not fullscreen.

And when it freezez on startup I can't CAD or something, reboot is only option :/

OK,

FH2 works in windowed mode
BF2 works either way
FH2 works if I start it through the Community tab in BF2

Something wrong with the startup in FH2 that my computer doesn't like?
