Oh...that would explain it yes! Oops.
I would love to check the new build to see if things have been ironed out, but that refund you did for me...it went through, I got the refund which I appreciate. However that also seemed to lock me out of further downloading the program's new builds... "This download page has been disabled and is no longer available. The purchase associated with it has been refunded." ...I imagine you didn't mean for that to happen. ^_^;
I know itch.io lets you hand over review keys/codes as a developer though... I'm a content creator and I've gotten some games for free via itch.io codes so that I could review them. Maybe you could toss me one of these so I can regain access to the program? You can contact me privately through Discord if that works; my username is 'charemplaysgames'.
