EXS 24 Logic Sampler Users Group

I had posed this in the general emagic group, then discovered this group, which 
seems more appropriate for my question. Sorry for the duplicate post in both groups.

I purchased Big Box, installed Logic Audio, did the 6.3.1 update, and all is
fairly well.

However, I went to install the Xtreme Analog CD, and it does not include an OS X

installer. I follwed the directions to manually install the files, including
placing the
presets in the exsp24 folder in Logic 6 Series > Plugin Settings. Since I'm
trying o the
exs24 demo, I also installed a copy of the presets in that plug in folder.

The Xtreme Analog Samples data folders are in Users > Shared > EXSP24Samples
and,
because I'm trying the demo module of the exs24, in Logic 6 Series > EXSamples

The Basic Waveforms Sampler instruments are in Logic 6 Series > Sampler
Instruments

There is an alias, Sampler Instruments, (which I did not create) in Library >
Application Support > emagic

The crash: In Logic, when I open the exsp24 synth, selecting any of the presets
that
appear in the triangular pop-down menu causes Logic to crash. The actual voices
are
accessible from the synth's black pop-up window.

In the exs24 synth, selecting a preset does not cause the app to crash, but the
synth's
information readout says MISSING: Basic Synth, (or whatever voices it can't
find). The
parameters of the preset load, but it only plays the default voice.

Yowza...

Help, if anyone can

thanks
