EXS 24 Logic Sampler Users Group

Hello out there,

I am fairly new to all of this MIDI stuff but I've been having a lot of fun with the 
EXS24 and the ES2 on my Logic Platinum 5.5 in OSX.  Until today that is!  I 
opened up Logic today and all of my audio files sound normal but every time I 
play a note on the MIDI keyboard (no matter what instrument) it plays as if it's 
20 octaves too high!  I tried lowering the octave on the keyboard but it doesn't 
respond.  I tried restarting the computer but that didn't do anything!  

Has anyone run into this before?  I am in a really bad position right now 
because I have a lot of compositions due at the end of the week and I'm really 
stuck!  Please give me some advice.

Bryan.
