Well, i read that it should take time but... after a few seconds I get an error which says "programm could not connect to blackberry". It starts installing and while copying "net_rim_cldc.cod" the BB restarts and i get the already mentioned "could not connect" error.
I can click "Try again" or "Cancel". If I click "Try again" it starts copying and then, the BB turns off and error.
This happens as often as i click try again.
Maybe I'm just too stupid (I hope so)...
