EXS 24 Logic Sampler Users Group

Hi. I'm having problems with AKAI converter on my EXS24. It won't 
read the AKAI disks even if I put it in after I go into converter. I 
called up the support and they sent me an Apple extension that 
should've fixed this problem but it didn't. I'm running on OS 9.1 in 
Power Mac G4. Also, I'm using Native Instruments Battery sampler and 
it does read AKAI disks but VERY slowly. So I wonder if there is 
problems with CD-Rom or extensions conflicting or something else.
Can anybody help me with this problem? Thanks.
