I beg to differ birdy, I cant tell you why my limewire 4.12.3 works perfectly but i can tell you i use xp pro SP2, windows firewall (on), zone alarm firewall (on), trend micro pccillin 2006, windows defender,and numerous other security measures running, could it be the type of modem someone has or their ISP? I'm with Telstra and use a speedtouch 500 series modem. Until joining the forum yesterday i thought everybody was doing the same as me.
From what i've read i was dissapointed to find so many people having difficulties. I wish i could offer some help.
