Hello guys, got a small problem here, I simply can't run FSO and I'm not really sure where to problem is. In general when I start it the exe runs in the Task manager but the game doesn't actually start. There is no error code, and i can't alt+tab it..

.
Concerning the installation, i think i got every thing right, I installed my original Freespace 2 + movies, (which is in German may be theres the problem..?) ran the installer "FreeSpace-OpenInstaller" and selected everything... . Well that did not work so i tried using an up to date build (the installer used 3_6_10 and I tried 3_6_12 the INF and the "normal" one... . Same result

The funny thing is that at some point the game actually started, it stared after i closed a diffrent game showed me the video and i could actually play (had all the effects disabled so it was pure FS2). But i can't reproduce the start. doesn't matter what options i select or if i start a diffrent game/close it.
It seems like the actually start of the game was just delayed by 1-2 hours 0o.
Anyway I got absolutely no clue where the problem is and I can't seem to find help in the guides

My Hardware is an AMD Phenom 2 with an 4870 ATI Windows 7 x64 (yes i used C:\Games\Freespace2) open AL is installed, and I also tried Opengl/Direct 3d...
Would be glad if someone could help me.
BTW when I start the game via a "D" exe it sends out an error:
