EXS 24 Logic Sampler Users Group

Just got my L7 today – excited to get it installed.
What a bummer!!!!
Logic 7 doesn't load half of my Sampler Instruments. They show up in the EXS's finder, but 
clicking on them nothing happens.
I can load them in the sample editor, it finds the associated samples and everything,so 
nothing's missing, but can't load them straight into the EXS.
Same thing goes for the supplied Garage Band Sampler Intruments – none of those will 
load. Again checking in the sample editor everything's there. Apple Loops load fine.
Sh...!!!!!!!!!!!!!!!!!!

Then I went back to Pro 6 to get on with my work – turns out now I can't load those 
Sampler Instruments in 6 either – they were working fine before installing 7.

I tried working it out via Project Manager, did a Repair Permissions, and nothing helps.

I'm ready to send this upgrade right back.
