EXS 24 Logic Sampler Users Group

I don't know why (I suspect that is when I open another song without 
closing the previous one) but sometimes when I open that song the 
EXSmkII load the instruments, but not the samples...I mean that you 
can't play that instruments (every EXS instrument) and the only thing 
you can do is reload the instrument, then you're able to play the 
samples...it's very boring I need heeeelpppp!
