Right, it uses that when you for example re-install Windows and create a new user with the same name as a user that already exists. It should be perfectly valid so I don't understand why it's saying the filename syntax is incorrect.

Sure, I would definitely go back to the working one for now. Sorry. I wonder if it's getting the same error when trying to save state?

With the working version, maybe try creating a savestate while paused? Then, check the debug log again. If it shows anything in red in the last couple lines, that might help explain why it's failing. I wonder if it's related to this 123 error you were getting with the git build...
