MPC 4000 Not loading.

Hi all once more,

Yesterday i had a problem with Windows 7 and Ak.sys and drivers to run the OS loader.

Today i've tried to install it through MAC once more, i've started installing it, and on the first few seconds he gave me error, that he can't update it and stopped it. I've tried to turn on my mpc and its not loading at all now, and computer no more recognize mpc by usb? Any advice? Help!! Thanks guys.

Anyone?

Unfortunately, and I as warned you yesterday:

if a problem occurs when updating the MPC4000's firmware OS, so that it gets corrupted,
that may REALLY screw things up and leave the MPC4000 in state where it cannot boot and you can't update the OS either.

It's the same risk as with the BIOS on a motherboard.

If your MPC4000 is in this state, you will need to take it to an Akai service centre.
