Try updating your OVI Suite to version 2.2 and see how you get on with that.

Also try another nokia with the same cable to see if you still get the problem.

If your don't I think you may need to re-flash your device just incase it never installed properly. If the other device does work then it's a application error. What OS are you using btw?

And just a quick heads up PR 1.3 is out now too. With that you can sync everything. The only thing that does not work that I have noticed is the Incoming call and text alerts that you get on screen. (PC Suit - Notifications)
