I've emailed Chris directly, but thought I would post here to see if anyone also has input.
After three months of using Chris Hein Guitars, I just started experiencing sudden crashes with both Kontakt 2 and the Kontakt 2 Player when trying to load certain patches. This only happens with larger sample sets, including the full sets for at least three of the guitars. It's consistent with both the Kontakt Player as well as Kontakt itself.
Even older projects that used these patches are now crashing K2/Logic when I try to open them.
I've been trouble-shooting to rule out various issues, including having reinstalled and experimented with new installations on two other drives. I've also played around with various DFD settings (though I've never changed these before with my slew of other samples). The fact that both programs (K2 player and K2) crash at exactly the same places might suggest bad files, though this seems unlikely as only the full sample sets seem to be affected. On the other hand, the fact that I can load the less-demanding patches hints at the possibility of memory issues, though I've never encountered this before.
In any event, I'm also experiencing some other glitches with projects where I'm trying to load the Garritan Cello - basically where I will close one open project, but Kontakt seems to forget to empty the samples out of RAM when loading the newer project (or that's my guess). Hence Logic crashes. The projects reload fine once I relaunch. Obviously I'm on a mac (G5 PPC, OS X.4.9, 2.5g ram).
Could these issues be related? None of these things have been an issue until recently. Any suggestions or help on this would be greatly appreciated.
