CPU Address Error

Does anybody know what CPU Address Error is or what I can do to fix it? When I turn on my MPC, thats what it says on the screen. It just started doing this a few weeks ago. Thanks for the help. McPhatty

A: If you are not using JJOS, get it.

I'd just try to re-install the OS, which you can download from the support section of www.akaipro.com. Be sure to also download the instructions on how to install the OS from the same place.

Those instructions could also be followed to install the unofficial OS (see the other forum for that on this board), if you want to try that.
