LW is compatible with Vista.


Did you try basic (free) LW first, before buying Pro?

It's a bit hard to help you, because you haven't even told us what your problem is (LW failing to install, installing but not opening afterwards, opening but freezing, opening but not connnecting, connecting but showing as firewalled etc etc).

Try looking in the General Vista Support section & see whether you can find any answers there. Otherwise, post back with a few more details
