Problem loading plugins/instruments

Hi guys!

I'm writing you because I have a problem that I can't solve yet, and I was wondering if you have some information about this issue:

I have an mpc touch and when I try to load an effect (EQ, comp etc), what ever it is akai, air, or waves, or any other plugin/instrument (from the arturia's collection for example), the software crashes. Just like that, losing all the work done before, if you could work anyway...

I've been writting to the akai people but they don't have any anwser!
I have a thinkpad I7 with 12GB ram, with only the mpc software installed.

I don't know why it would do that. Right now I can't even't load a plugin, instrument or anything. So,

Any information would be appreciated!!

Peace

I've noticed that opening the plugins from the pc (instead of the MPC) doesn't make this problem happen

Any idea?
