MPC Wont Show Transfered Files From PC

It shows it on the flash card when hooked up to the MPC, as well as transfers fine on the pc side of it. But when I try to load it on the MPC, the file isnt there. WTF. Itll show the new folder, but wont have anything in it. I tried to reset it by using the "hold erase while turning on" method, but still no luck.

your samples need to be 44.1khz 16bit for them to show i believe...

Yup, and if it aint that their corrupt.

that have to be .wav files too, not .mp3
