Which version of Pro do you have?
A court injunction is preventing LW from distributing their software. Also most of their servers have been shut down. In effect they are in a way shutdown yes. But the company has not closed. They are working with the RIAA to keep afloat is last thing I read. That means LW will not be the same & will probably become as Bearshare, Shareaza & iMesh became
