Hello, i've been a user on limewire for a little while now and i just got limewire pro 3 days ago; i never had problem with the speed before and since i've installed the pro version the speed is suddenly dropping at zero everywere but i can still do my search and it says i'm connected!! i've tried everything(i think!)i disinstalled it to put back the basic version, I tried configurating my firewall and add tcd and ucd port; i don't think it's that cause my firewall is not blocking limewire (the globe in the left bottom corner is ok and the host are conneting; but anyways i come here for help now i'm lost!!!! I'm still new at this i've just starting working on a computer(home) since 3 months ago( i know i have alot to learn but still) My pc is a 1ghz, i use a dsl modem connexion, 256mo memory ram and i have windows xp sp2( tweaked ) on my pc and i use window's firewall"""""" Sorry english is not my first language......
