EXS 24 Logic Sampler Users Group

HI, I just installed my exsp24 AU and transfered the .pst files that were in my exs 
folder (Logic->Plug-In Settings->EXS, moved them to Logic->Plug-In Settings-
>ESXP) from the Xtreme Analog disc that came with the Big Box. They show up in the 
exsp, but when I try to access them it crashes Logic, every time. I am running Logic 
Audio 5.5.1 on OSX (10.2.6), 640mb ram, iBook (800mhz).
The XtremeAnalog disc should work with the exsp24 right? It was fine on the full exs 
with the same system.

thanks,
