I have already purchased affinity designer 1.6.1 for Mac OSX Yosemite the beta 1.6.1 RC1 says I must buy retail version. I thought about inputting my order ID on my receipt through my online account through your retail store but there is no such option. I have tried uninstalling the app and reinstalling, I have restarted my computer after installing the beta. I read that the beta should fix all the crashes happening with this version, which is why I want it to work. are there any other options at this point? does OSX Yosemite not allow for the updates? are there any other beta versions that might work better?
