okay i filled out those questions, sry if i did a bad job. haha im not very smart with computers at all. so i have one green connection bar and on the connection pannel there are different numbers but the longest i will stay connected to any of them is 15 seconds and then it disconnects and goes back to 0:00. I use mozilla firefox as our internet (instead of internet explorer) and i disabled the pop up blocker for that. i already went in to windows firewall and did all the port adjusting and such for gnutella. this is really frustrating me, and i would LOVE it if someone could help me out...(and please remember i dont know much about computers, so in simple english would be great!) alright.

i really appreciate your help on this guys. thanks
