EXS 24 Logic Sampler Users Group

I just made my ' first'  instrument with the EXS24.
At least, I tried.
When I created it, I heard wonderful staccato bariton sounds.
I saved it. But now I restarted Logic, the instrument is visible in the 
arrange-window, all other EXS24 sounds work fine, but not my bariton.
During the time I should hear the sound, it gives noise instead.
Could somebody give me a hand with this.
