Later today the IP of the server is probably going to change (my service is being upgraded). For some reason (which I can't remember), the IP is hard coded into the code. Which means that when the IP changes, the auto-update will also break.
So you'll have to download the new code from the site (once I fix the new address).
Once things are settled, I'll spend some time making sure this goes easier in the future. For now, please bear with me.
Edit 7/30: Ok, it didn't happen today (AT&T is run by Satan and his demons). Will update when I know more.
