There is an update, but the server that hosts the updates is still having DNS issues (en.wikipedia.org/wiki/Domain_Name_System). If you were getting "Your database is up to date" then you should now be able to get a 5/20/2013 database. If you were getting "Timeout" then you might still have problems.
Thanks, Upman. However, I have gotten the same 'your database is up to date' message each time trying to update from early Monday morning until just now. I have tried multiple times each day hoping that would change. So I think something else might be up with that. Just thought I'd pass that along in case it helps. Thanks for always 'being there' for us all. You make a big difference.
