Currently, I am not able to use my N900 due to an "internal error":

- I had to flash my N900 with the newest update fremantle-1.3.
- Next, I restored my contacts and calendar data from an OVI-suite backup.
- I was able to open the contacts application for a short while but then it crased.
- Now, every 10 secons or so a message appears "Internal error. Program contacts closed"

Flashing the phone again does not seem to be an option. How can I resolve this problem?

Any help greatly appreciated since I currently cannot place phone calls!
