port locked / another application using it

[arron]

Little bit green so bare with me please....

vista basic...avg free..windows def...3g ram.. 360g hd..cable...motorolla modem..netgear w/router wgr614...home connection..lime version 4.9.37.. java version 1.6.0_11...optus...test worked...yes brick wall..

Installed limewire and no connection...Asked around and was advised to manual port forward.. I did this and tripple checked things throughout the process making sure it was done correctly.. finished this process including avg/exceptions/limewire and still single bar?..So i did a port check, came up with error "port is locked, another application is using this port" Disconnected lime wire tried again same result. I have tried "start/run/cmd,,with various netstat combinations to find out what other application are using this port but nothing worked. Both port numbers are 50000(tcp)

just when you think you got, another problem...

any advise would be much appreciated..
