Internet Connect not working

[Milan100]

hi, my internet connect isn't responding. my n95 is hooked up to my macbook and bt is working with synchronization. in the past also internet connect was working and i could use my phone as a modem. now, every time i open my macbook the pop-up comes stating that internet connect isn't working.

i can't even open the application. any ideas what to do. can it be reinstalled or ...?

thanks

I Leopard open System Preferences->Network and follow the BlueTooth connection buttons.
