Starship Troopers - Ends without ending.

Starship Troopers is a cool 3D shooter, I run out without running out. I got to the Offensive level (Fort Raszhack or something), go through it and that's it. The game goes to the main menu and nothing else. Playing on DVD, no problems with installation, all videos and introductory documents (info about bugs are present), that is, it looks like a truncated copy of a copy, but not so much. I looked at the installation folder on the C drive, and so there are folders of levels in which I was and in which I was not + all audio files are present (such as the mission on the mission in which I did not play, and the rest). there are levels according to the data, but not during the game? Does anyone know what kind of trouble this is? Help can you do something.

PS I have the same, in principle, bedala in AREA-51, the current there igruha vnature truncated, on cd, I was carrying a video, without everything.
