EXS 24 Logic Sampler Users Group

Hey I just started messing arround with the Wizoo Latin Percussion 24 EXS version.  But on 
a lot of the EXS instruments, when I load them, EXS says that it cant find some of the AIF 
files in the instrument.  At first I thought that I forgot to copy some of the samples over 
but then when I searched my HD for the files it said were missing, they were already there.  
So then I checked the EXS instrument files to see if the Wizoo people programmed them 
wrong but the file names are all correct.  So in the instrument editor I tried manually going 
through all the zones and reloading the files (even though all of them already had the 
correct file names) and it worked.  However a lot of the instruments have tons of velocity 
layers (e.g. congas) and that would mean I would have to do that for like 40 or more 
zones per instrument.

So basically my question is this: is there any way to have Logic re-search all the targeted 
files in an instrument?

I thought it searched for the files everytime an instrument is loaded.  I guess I was wrong 
or otherwise this shouldnt be happening.

Thanks in advanced.
