OBEX Errorcode: C3 - Forbidden - operation is understood but refused.

Copy of the first lines of the logfile:

Could somebody help me here. Please.

I tried to uninstall and install the old 1.6.4 but now it will not even start.!

It has nothing to do with thw Version of MyPhoneExplorer. The error comes from the phone. Restart your phone - maybe it helps.
