I was having problems with pockettwit and pie was really slow, so I decided to do a hard reset and reinstall everything to clean things up.

After the hard rest, I cannot install any cabs except for Kinoma freeplay. I get the message:

Installation of [cab file name] was unsuccessful.

I have tried:
Google maps
Skype Mobile
Pocketwit
SRSWowHD

Any ideas of what is happening?
