EXS 24 Logic Sampler Users Group

Greetings All,

The other day I opened a Logic song that I had been working on the 
previous evening, opened up what should have been the EXS24 mkII only 
to find that it had been replaced with an older version of the EXS24.  
The EXS24 mkII is nowhere to be found in any projects where I had 
previously used it.  I have permanent authorization for the version of 
Logic I'm running (Platinum 5.3/Windows 2000) as well as all of the 
software instruments that were available as of that version.

Any idea what happened and how I can get mkII back?  Thanks in 
advance.  John F.
