Hi some1 help

I am running on xp
Have aol 9.0 1m b/band
Use norton 04 pro


I have no trouble in connecting to limewire, but after a couple of minutes, it disconnects and an error comes up telling me i either have no internet connection or my firewall is not allowing traffic.
I have found that the problem is that limewire takes over my whole internet connection and overrides aol, aol doesnt shut down, but will not allow me to download or search in aol or limewire. I then have to restart the computer to enable aol to run again

please help me
