Default MIT app inventor apps not working on O2x cm7?

Tried to develop app using app inventor but app crashes on start always. Also tried apps others have done via gplay but they crash too. Have any p990 users been successful developing or using appinventor apps for o2x on cm7?

Look for hellopurr in gplay store to test.

SOLVED: OMG so simple but hard to find and annoying. Just needed to disable auto-rotate screen.
