Trigger sounds in logic audio

Hi!
I used to trigger sounds in logic audio platinum 5.0 with my mpc 2000 xl. Since I pressed "Initialize all parameters" in the "Other" menu this is not possible anymore although logic is still receiving a midi signal when switching on the mpc.

Any idea in here?

Thanks

Now it's working again , I had changed the driver settings.
The mpc was innocent.

peace
