I have recently downloaded the newer version of limewirepro and now i can't get connected. It keeps on saying connecting but nothing happens. I had no problems with my older version. I have windows XP. If anyone can help me i would really appreciate it.

Did you configure all your firewalls: http://www.limewire.com/english/content/firewalls.shtml

Try Fixes for Limewire to see if that helps.

Just happen to bump in this thread,

Do you have a router?
Something might have changed and you need to configure the router, sometimes the assign IP will change so a new rule needs to be made.

Here is a link to find your make and model of your router if you have router that needs to be configured or sould I say configured again.
