Download and assign sound packages

Hi,
I just bought an MPC touch but I can't use it cause I have no sample/sounds to assign to the pads. I downloaded the free sound packages but when I try to open them on the MPC to assign them, files such as "Essential instruments" are empty (*image below). It doesn't show anything when I open it. The solution may be very easy... but can anybody help me?

Thank you very much!

You'll need to upload your image to a free image host and link to that.

BTW, Essential Instruments must be opened in the 'Expansion Browser'
