hi Samantha sometimes if your downloading from like 1or2 host it will stop downloading try right clicking on the subject your searching for or the file your trying to get and get more results if it don't get enough i just keep doing that till i get more lol hope it works for you also if its getting all junk try clicking connections and remove them if you cant see connections click view/showhide put a check next to connections. sometimes you connect to bad/rouge peers and a good program to get is peerguardian it blocks a lot of known anti p2p hosts you can get it here
Phoenix Labs PeerGuardian 2 if you don't have it. if that dont work keep chicking back for more advice good luck.
