I agree with Boyfunk. Don't give up!
- You had a good thing going, It was part of who you are!

Put up something temporary, to let your users stay in touch, like a phpBB board - free and installed in minutes!

Then let them know that you're working on reestablishing the service (NOW!)
But this time, use open software, that you can tweak or redo to fit your needs...

"Encrypted scripts" - bastards!
