the Pro update lookup is being bogged down ( I just tried and got the same message), but my bookmarked Pro page loads right way in Safari.

Do you have your Pro page bookmarked?

If not, you can get an almost-equivalent-to-Pro from the open-source build of LW in the meantime, thanks to Jens-Uwe Mager http://www.mager.org/LimeWire/LimeWire.html
