MPC-Samples.com Programmes are Pitched Wrong?!

Hey everybody!

I bought the "Ultimate Multisample" Collection from MPC-Samples.com today, but soon i noticed that all programms are pitched one semitone lower then they should be.
Did any of you have the same problem?
Is there a way to fix that except from re-pitching the whole programm one-by-one?

Thanks for your Help!

just speed up the final recording a little and youll be cool

I have a few of those kits and never noticed this problem...
