Connection ok, but firewall blocking downloads

[Lorrinda]

I used to have a dial-up connection and didn't have any problems downloading before. Last week I went with Satelite Internet (Xplornet) and now when I start up Limewire it connects ok, but when I try to download, starts to download and then stops. I have been trying all day to download just 1 song. I have windows firewall disabled and am running Norton Internet Security 2008, but I set the setting under personal firewall to allow Limewire, even tried the custom setting. In Limewire it is showng a brick wall in front of the blue world icon. if this problem is to do with my new Surfbeam Satellite modem, I do not know how to fix it. Any help would greatly be appreciated.

Downloaded a couple of songs this morning. The brick wall was gone from the globe and then it came back again. Downloads started getting slower and now not able to download anything. Just keeps saying Waiting on busy hosts or need more sources. I have tried other downloads and same problem. The greenbars are still showing full though, so I do think that it is something to do with this new internet high speed that I just got. Someone please help.........
