It expired because it was a beta. Active beta testers who provided feedback got a copy of the updated version with WP3 updates included, etc.
I have been using this software and love(ed) it.
Assuming that beta testers here only got a trial copy? Started it up this morning and got the message license.dat has expired.
Please let me know. Would have contacted you at your site, but there is no info under your support area. Noop so can't P-M
