Limewire doesnt work and its the same problem like everyone else seems to have .. the connection. I only get one green bar connection.

I had this problem before, because a few weeks ago we had a virus and we decided to reinstall XP again. So all the files on our computer were lost. I reinstalled Limewire again and i had no problems for a day. The next day Limewire couldnt connect for more than 1 green bar. I looked up the forums, and i found the suggestion that i should delete the .limewire folder. I did that, with no luck. Then i tried this suggestion:

And it worked, and i was so glad. But now, after 3 weeks, it doesnt work anymore. I tried the same steps as above but nothing i do seems to work!
I only have one green bar connection and a brick wall in front of the globe. We only have one firewall and thats McAfee. And the most frustrating part is that on my computer we have five accounts, because its a family computer. And we all have Limewire and on all the four accounts of my brothers and parents, Limewire works perfectly. And they all have the brick wall in front of the globe. I tried to put the digits they have in their "Listen on port" in the Options>>Advanced>>Firewall Config. but that didnt worked either. My ISP is Wanadoo, but they've changed their name into Orange.

I dont know what to do anymore...
