I moved my web hosting from Rochen to HostGator. I still have some things that need to be setup still but rest assured that I will get everything back up and running in short order.
As of right now, all downloads for my programs should be working as of right now and all version checking functionality should be working as well.
WordPress is running very well on this new server, far better (and faster) than it was running on the server that I was on at Rochen. So far, HostGator seems to be working pretty well for me.
