Limewire won't intialize

[Computer Moron]

I had limewire previously... and it cot completely deleated from my system I tried to downloaded it again and when it was wfinished and sould click to start limewure i got the message:

Limewire was unablt to intialize and start. This is usually due to a firewall program blocking Limewire's acess to the internet or a loopback connections on the local machine. Please allow Limewire to acess the internet and restart limewire.

I do have spy sweeper and norton antivirus, but had them disable when i downloaded. I do not have a firewall up. I read how to allow Limewire to work with a firewall w/ window's XP. The proble is that when it asks me to go under tools in limewire to get some info, I can not open limewire to get the info. I do have high speed internet and it is working fine. the old version of limewire that i had was working fine yesterday morning. PLEASE HELP!!!!!!!!!
