Just bought LimeWirePro today, and it keeps insisting that I haven't installed Java 1.3.1 (btw, the link on the install page takes you to the most recent version of Java, but whatever, I managed to find 1.3.1). I have loaded it, reloaded it, uninstalled it, checked repeatedly in the task manager to be sure that the install was not hung, all to no avail.

Any advice?
