http://www.ultimateauction.net/ currently displays a "Hello World", a quick look back via the way back machine shows few changes. A cautionary note, security wise there are some CVEs which should warrant some investigation. It's closed source and there seems to be no documentation detailing dependencies that I can find. Perhaps the suggestions I made earlier would help make that part of the task easier.

Another way to look at is that your $300 investment in 2001 seems to have served you well until now, perhaps it's worth while looking at alternatives?
