Getting AAE Error -20038 trying to add MPC Beats (Akai MPC225 won't work in PT)

[BLG]

Long story short I bought an MPC225 controller and I can't get it to work in PT. (Add an Inst track, add insert Xpand!2, clicking on piano roll makes sounds, but pressing keys on keyboard does not). So someone suggested that I create a file in MPC Beats and then import it using the MPC Beats plug-in, but that won't load (generates an AAE error -20038 - see attached).

I've googled it but found nothing on -20038.
