EXS 24 Logic Sampler Users Group

I've added memory now @ 3Gig, got a fast processor @ 2.8ghz, 
multiple SATA drives, yet when I go to load the Old Lady (even 16 
bit) I'm told it can't load all the samples...

What am I missing?  I've shelled out $80 for something I can't even 
fully utilize in our studio and it's driving me nuts as the 
keys/combinations that do load are marvelous.

Any help would be appreciated.

I'm running LA 5.5.1 (pc)
3 Gig memory
2.8 Ghz P4
2 160Gig Sata drives

Thanks, Reid
