For some reason limewire only connects on my sisters profile and not mine. I find this strange because i installed Limewire in a shared system folder and my profile is set as the system admin. Im running windows XP.

Any ideas on what could be wrong?

Try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #3 in Fixes for Limewire (sample image included at bottom of page.) or if using Vista see http://www.gnutellaforums.com/genera...der-vista.html

Then after opening LW give it time to connect. If no connection, try changing the connection port (to one between 49152 - 65535) listed here: Tools -> Options -> Advanced -> Firewalls. OR if using LW 5, change these settings under SuperReallyAdvanced section.
Need to make sure both LW's are not using the same connection or listening ports.

Thanks alot. Changed ports and now Limewire works on both accounts!
