Have a server update. I FINALLY got my machine to unregister. There was a lot of stuff I had to figure out and account for in the unregister protocol and I still didn't get it 100% right yet but I got it good enough that my machine unregistered. After unregistration I was not allowed to do a force call or anything, my screen changed to this:

When I select to register I get prompted with the following now:

This is great because we won't have to use an operator card. I can give everybody a unique 4 digit code and then that machine can register. Obviously I now have to analyze and handle this new registration process but it will be a LOT easier than creating bootable CD's and nudging the machine to do the right thing. It natively wants to do it hahaha.

This might only be for the TC version software though. But at least it's a start.
Spitfire, you actually forced a call correct?? The error you got was 4010 right? That error means the cabinet does not have an ID from the server BUT for some reason you were able to make a call. That means the software believes the cabinet is registered but the dongle thinks it is unregistered. Am I correct or are you able to see the same menus I have screen shots of above? If you don't see these menus then I think we need to attempt to unregister your machine using the private server. I will put the server back online tonight and upload my latest build. You should be be able to select the unregister option, make a connection to the server, you WILL get a 4000 error but after that your machine should be unregistered like mine is now and you should see the same menus.
Next thing for me to do is write the logic for this 4 digit code registration.
