EXS 24 Logic Sampler Users Group

i'm trying to use the sonic implant dvd library in the exs, but I'm getting alot of clicks on 
playback. the library is 48k, but I've converted a bunch of samples and it doesn't seem to 
make a difference. BTW, I get the occasional click with the rest of my library, but it's much 
less pervasive. I've got a dual 800 running 10.3.6 with a motu 424/2408 and logic 6.4.2.
has anyone out there had anything like this problem?
Thanks
