Sad to report a glitch in Moebius. At the end of Chapter 2, after the final cut scene, the screen goes black. I still have access to the menu and it indicates "game paused" but I haven't found any way of "un-pausing" the game. I have tried "return to game" and other menu options and I've replayed from save and even started all over but still get "game paused". If anyone can help I would sure appreciate it. This is such a great game. I cant help but wonder if this problem has something to do with the demo that I loaded and played earlier; The demo ends after Chapter 2.

It does sound like it might have to do with the demo.
You could try backing up your saves, uninstalling the game (and the demo if there are remnants of it), and reinstalling the game. Does the demo show up as a separate install in your Programs list?

You could also try asking for a saved game from near the start of Chapter 3, and see if loading that gets you past the "sticky" area.

You might also try posting at the developer's forum (Phoenix Online forum) in their tech support for Moebius forum at
