navigami

Hy. I am the owner of two Blackberry's. One is 8707 g and another is 8110 (with build in GPS Antenna). I have installed navigami on 8707, seemed to be ok, but when I start the apllication, the phone is "dead". The keys won't work at all, any of them. But i tried to receive a call, and it worked. I will soon get a 8800, can I get the program to work in any way?Thanks and I hope you replay.
