downloads go from 15kb down to 1 , 0kb within a day

[delirious]

Hi this might sound abit repetitive but i am having download problems. I have recently switched from limewire to limewire pro thinking it might make a difference but the same thing seems to happen. I am on a 100mpbs connection as it is networked so im not sure which setting to have my broadband on.Also I am on tiscali so it might be something to do with that and i cant seem to adjust my incoming sessions from false to true even tho i turn off windows and norton systemworks firewall.Could somebody please help me if possible oh and also my modem isnt on the port fowarding website.Thankyou very much.delirious
