I recently sold my MPC1k with JJ OS2, and bought MPC 2500 with the free JJ OS, Version 3.10.
Now I'm having problems with it, and I really hope its just the OS, not the machine.

So the first problem is;
When I insert my old CF card in the MPC2.5k's memory card slot and I turn the MP on, it starts running but only with a blank screen, it doesn't even show the memory upgrade thing or which version it's running, just a blank green screen.

Is it because I use JJ OS2 formated card with free JJ OS?
If so how do I format the card?

And today, 15 minutes ago I lost my 4 hours of work because the screen froze, same problem.. It only shows a blank screen and I couldn't get my work back..

But anyways, I'm thinking about upgrading to the JJ OS2XL because I really liked the JJ OS2 on MPC1k, but I don't want to buy a new OS before I know if the problem is in my MPC or is it just a JJ OS bug.

Give it a trial with the standard akai OS and see how it performs.. Then you'll know.

Also. To format your card insert it after you've turned on the mpc.. I can't remember the exact location of it cos I dont do it much.. But it's accessed either from the load or save windows. The jjos online manual has pretty clear instructions about formatting cards and hd's

Hopefully your not gonna lose anything tho
