trying to load without any luck

I cannot load anything on to the mpc 500 I get a " not enough space available" message but there isnt anything on the mpc. any suggestions?

press status and see what your at.
is your autoload on? maybe something is holding up space.
or if your expansion memory is messed up maybe thats it.

i never had this problem but im just thinking what i would check out

I am a little ignorant to this new equip.

At least... Do you have a memory extension man?
Because if you don't, then some programs won't load because they are larger than the initial 16 Mb of internal memory...
If so, you definitely need to invest in some additional memory man.
