Are you saying you are upset that you couldn’t use an unreleased new version, and that you had to resort to using the version you had actually purchased? Or did you purchase V2 before it was released as a sort of pre-purchase?
I am not claiming you ripped us off or that your product is no good. Pretty sure we eventually purchased 4 licenses, because it is a good product. But better communication, taking the whole thing a bit more seriously, would go a long way. You knew what day the betas were expiring, instead of leaving all the customers hanging, you could have proactively sent everyone license keys or a longer-expiring version. You could have posted a quick status update on your web site. As I mentioned in another comment, I vouched for you internally and when asked about it months later (budget reviews, etc) with still just a beta version, I didn't have any answers.
