Hello hopefully someone can help me.My problem is this,When i try to connect to limewire i keep getting this message:
Limewire is currently connecting to the network,your search may not return many results untill you are fully connected.I wait and wait and it never connects.
Now i am not real computer savvy,but I will answer the questions as best i can.
New computer so i'm sure i have the latest version of windows.
Firewalls:I have Mcafee,and possibly one from windows(not sure)
Ram: no idea
Disc space: im sure alot,since i dont have much on here yet
Connection: cable
Modem Router: dont know
Connecting from:Home
Limewire Pro.....Java:dont know
ISP: dont know
Test: said it worked
Sharing: no only computer

In LW, click on Help then click on About LW...that'll show you the LW & Java versions that you're using.

Who do you pay for your internet (which company)?

What boxes plug into your computer so that you can connect to the net? Have a look on top & underneath, tell us brand & model number.

What type of Windows do you have? Is it XP or Vista (what shows up on the screen when you turn your computer on)?
