I thought that might be the problem but since I don't know where to look for solution I didn't know what to do
Well, if you have someone to test the PIN message with, I would do that as it can narrow down what the possible problems are.
You also might want to try registering the device with the network again. Do a reset by pulling the battery for 30 seconds, put it back in and let the BB boot. Then go to Options- Advanced Options - Host Routing Table, press the menu button and choose 'Register Now'
