Forum to discuss all matters relating to the MPC1000 and MPC2500 operating systems created by 'JJ' (all versions).

I picked up my MPC a decade ago and didn't really use the JJOS installed.

The other day I began using it, but then needed to buy a password.

I bought the password, entered it, and the device continued to work.

After switching it off, I now can't save anything because a new product ID has been generated on the MPC, and it required a new password.

Any tips for dealing with this?
