Hi i'm having the same problem (on windows 8 ).
I open the game, doesn't launch, try it in admin-mode, press yes, nothing happens.
Tried running all different compatibility options, didn't work... at all!
Deleted my RGL_config files, deleted the Appdata part from my documents folder, reinstalled the game four times, updated direct X, redistributables, video card drivers, tried steam version, non-steam version... i'm at my wits end...
Edit: Don't have a copy of RGL-LOG for you, seeing as the game doesn't even come far enough in the boot process to create one....
