EXS 24 Logic Sampler Users Group

Has anyone experienced any problems with Logic 5 and the 
EXS24. Just upgraded from 4.8.1, and EXS is taking a 
painstakingly long time to load.

I have transferred my EXS libraries to new machines in the past, 
so I know initially the instruments have to be rescanned and 
found etc., etc.

I started off with the EXS demo library that is built into the V5.0 
upgrade. Worked fine. I then transferred in my 20-25gb library of
Sampler Instruments and EXsamples, just drug from old V4 
folders into V5 folders. Reloaded EXS, now when I choose an 
instrumen, nothing happens, there appears to be no searching 
or processing of any kind, I waited for upwards of 5-10 minutes, 
and nothing happened. 

I ran another test, I emptied my V5 EXS instruments and 
samples foldrers, and just left one folder  say :"Distorted Reality" 
in the folder, reloaded EXS worked fine, I then added another 
folder of the EXS Factory Instruments, worked fine, then I 
dropped the whole library in again, no go?

Are there any limitations on EXS24 initially in V5.0? It seems I 
read in the manual that full REX2 support in EXS was not in 
place until the official install of EXS happened(entering codes 
into XSkey).

I also noticed a folder at the very top of my patch lists from the 
pull down menu in EXS  called "untitled". The submenus of this 
"untitled" folder appear to have a carbon copy of my entire EXS 
patch library. Does anyone know what this folder is for? I couldn't 
seem to get rid of it? Does it anything to do with saving EXS 
samples with your song?

Sorry if this all obvious, after several hours of tweaking, I am 
clueless?
Thanks
