I tried doing a search of the forums, but it won't let me search for XP.

When I initially installed Limewire, I opted to disallow other XP account users - on this machine - to use it. I would like to switch that now and allow them to do so, meaning other people who log into their own XP desktops on this computer. How can I change that?

You see, initially I didn't want my teens messing with it as it has gotten us into trouble before. However after much drumming into their heads about being careful, I'm willing to give them one last chance.

Any ideas? Or do I just have to uninstall/reinstall?

Erm ... I'm not an XP user & not sure how you disallowed them other than perhaps changing permissions of particular programs. The easiest way to share LW between accounts is normally to create shortcuts to the program & send those to either or both the othert accounts' desktops & Start menu > Programs folders.
