cant connect get error message lime wire was unable to set up port to listen 4 incoming connections.Shut down firewall in ISP and in F_secure.I run XP.

Make sure LW is given clearance thru your firewall; Windows Firewall - LimeWire

This might be worth looking at too www.LvlLord.de - Tipps, Tricks & Utilities - Tools

I checked in windows under network connections and I see no limewire there.can I manually install this?

I'm not too sure what you mean...do you mean that you're looking in the Windows firewall exceptions?

Try deleting LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

Start LW & see if you still get the error message.
