Was hoping for that update too, but it didn't help, still freezing like hell.
Recording for bout 15 Minutes worked fine, then replacing IKmultimedia EQ with Presonus EQ and.....freeze.
I updated all my Waves plugins, IKMultimedia Plugins are newest version, so S1 5 just sucks, everything works fine in S1 4.
Very very dissapointed, this Software is absolutley useless for me.
