The google play app seemed to work fine after install, I was logged in with my profile and all. I had install one or two apps already.
What then happened was that while I was installing a new app the googlel play suddenly crashed on me.

Now it is still there, but the credentials seems to be in some kind of half-assed state. Even if I reinstall play, or even do the complete reinstallation of alien dalvik (by clearing everything in /opt/alien like klippe above), it seems as though it don't know what apps I have currently installed and it doesn't show anymore what apps I have bought earlier. How do I reset the credentials for android on the device so that I can specify the accounts again?
There is no option to choose or add an account anymore.
