Captivate 6 crashes at startup

I have installed Captivate 6 (Demo) on my Mac (Retina MBP with MacOS X 10.8.2). Whenever I try to create a new project at startup, the app crashes with the following message (in german, sorry)

"Schwerwiegender Fehler. Die Anwendung wird beendet. Adobe Captivate hat versucht, Ihre gesamte Arbeit in den entsprechenden Projektordnern als Dateien mit der Erweiterung „.cpbackup“ zu speichern."

The Console log gives me this:

Any ideas?

thx
