Crash after intro sequence

[brogan]

So i just downloaded the mod, "installed" it (steam version aka put the folders and batch datas where they belong to) and tried to start it.
The "Stormtrooper loadscreen" went over after approximately 30 seconds, then the cutscene was showing but after that cutscene it just crashed with an exception error. Now i installed the ramfix and it doesnt show me the exception anymore but simply crashes to a "xyz doesn't work anymore" window.
Ideas would greatly be appreciated

UPDATE:
After Reinstalling the game and erasing the folder-left-overs i now get into the main menu but upon clicking single-player i get an direct3d error 

UPDATE2:
Well, now it literally doesn't work anymore. After seeing the stormtrooperscreen it just crashes... This game isa horrible mess ~.~  also i cant install the official ramfix. while it finds the installation path, i get a message where it says, that its unable to install, without giving any reason.
Now I'm absolutely clueless ._.
