JJOS Issue with MPC 1000 XLCD

I've had an MPC 1000 with and XLCD screen and the free JJOS that was provided from MPC Stuff on Compact Flash card. I've installed JJOSXL to see what extra features were on. Once done i tried to revert back and install the free JJOS that was provided with the XLCD screen but it keeps asking me for a password. Does anyone know what to do?

Thank you

Had the same problem with my MPC1000. Now own the MPC2500. The problem has to do with adding the XLCD screen, MPCStuff has this problem documented and will be able to help you out.
