EXS 24 Logic Sampler Users Group

Hi, tried to search for this in the archives first but didn't find 
anything. I'm using LE 7.1.1 on my iBook G3 running OSX.3.9 with 640 
MB Ram, and just recently I've noticed that all of the factory 
samples/sounds in the EXSP crackle. None of my other samples do this 
(or any other soft synth instruments), and it does it consistently - 
even if I create a new song with only one instance of the EXSP, 
nothing else, and load ANY factory sample - so it's not a CPU 
overload. I'm trying to figure out if I have to re-install the 
samples or if there is some other possible fix. I remember hearing 
about a feature to fix samples with the assosiated instruments - but 
I can't find that. Is that feature only in the PRO software version? 
If I DO have to re-install the samples should I delete the old ones 
first, or let the installer over write the existing ones (will it do 
that?) - and lastly does any one remember if those samples are on 
the 7.0 installer disc, 7.1 update disc, or do I have to get them 
off my LE6 discs?

Much Appreciated
