3 accounts, 1 doesnt work

[TheLazySamurai]

I have 3 user accounts on my PC. 1 account is an admin and the other two accounts are limited. The admin is not generally used. The limited account that Limewire works on is mine. The other limited account which Limewire does not work on is my dad's. As well as i should mention that the settings on all of the different accounts for LW are exactly the same as I set them all up. Just putting that out there for refference reasons. When I go into LW on my account everything works fine. My dad goes on his and a firwall is blocking him. I go onto the admin account and LW works fine. I looked through alot of different threads on these forums about firewalls, multiple account issues, etc. but could not find one that either pertained to my situation - or if it did, it did not solve my problem. I have gone through the firewall exception and I use the UPnP to optimize my firewall and router as it says. But for some reason my dad's account just will not work. I have a windows XP home edition completely up to date. The only firewall I have is the windows default one. As i metioned above, my account is limited as the same with my dad's. I have been at this for quite some time now, and would appreciate any help I can get. Thank you in advance.
