If you're on Windows Vista or Windows 7 this is usually a file permissions problem trying to read the two configuration files mobius.xml and ui.xml. If you're on OS X there are similar issues with /Library/Application Support thought the installer usually handles those. Let me know what OS you're using and we'll go from there.

Subject: Möbius weirdness
So I was cleaning up my hard drive yesterday and deleted a bunch of files that I didn't feel I needed any longer (audio files mostly) and somehow the graphic interface for Möbius disappeared. The program is still there but the screen is white.
Okay, so I screwed up and deleted what shouldn't have been, no problems. I deinstalled möbius and did a clean install of 2.5 OS. Same problem. I've repeated the clear/install routine several a times since (with reboots aplenty in between) and I still have a blank möbius.
Any ideas what I've done or how to repair the program?
Till now you seriously considered yourself to be the body and to have a
form. That is the primal ignorance which is the root cause of all trouble.
