IMO the fault lies more or less with PG's marketing advertisements ... if an inexperienced PG newbie is not familiar with the way the PG system works, they must have believed they bought a full blooded BIAB VST work horse with version 2019 .... alas, not yet.

PG could reconsider their advertising, sounding more like: hey buyers, stop moaning; you get 40% off in december; see it as a beta tester discount. Thereby allowing us to get your opinions and bug finds to improve coming updates during the coming 6 months.

I must say the essential fixes up to 607 came rather fast. Before Xmas even. I've been working with the 64bit version a while now, and cannot find problems regarding my ways of using of BIAB other than that the VST still sucks, and the stylepicker has some built in search faults. 607 seems very stable, no serious crashes, just found only one i can deliberately force happening. And the amount of RTs, you can spend weeks checking them out. Some amazing stuff in there, and i still find good things among the older RTs .... It's been a while since i really needed to hire a musician for some demo recordings ... An i just downloaded 608 smile -F
