EXS 24 Logic Sampler Users Group

Hi All:
I'm wondering whether someone here might be able to help me solve a vexing sample 
organization problem. 

What happened is that I bought 25 gigs worth of instruments and samples from a
friend,
who brought them over on an external FW drive. I hooked it up to my Powerbook
and
dragged all that stuff to my external FW drive. Then I took the instruments off
that drive
and put them in this folder: /Library/Application Support/Logic/Sampler
Instruments.

Then, after I experienced a half-hour wait when loading one of the new EXS
instruments
once or twice, I went into Project Manager, selected the Sampler Instruments
folder and
chose "Find unresolved file references for selected items". Initially, I got
error messages
along the lines of "you don't have permission to change this file". I went and
changed
permissions on the relevant disks/folders, which solved that problem. But the
instruments
and files remained stubbornly unlinked.

Then I bought EXS Manager from Redmatica, set it to relink the Sampler
Instruments folder
and the folder on my FW drive that contains all these new samples and let it do
its thing.
Still didn't work.

Any ideas? I've read some confusing things in the LUG and EXS archives, as well
as in other
places online, about putting aliases in folders, but I didn't really get it. Do
I need to do
that? Tia ~ mike
