So i bought screenflow 3 off macupdate.com and now with a new macbook, i redownloaded it from the site and entered the serial number listed for it. When i enter the serial number, it tries to get me to "upgrade to screenflow 4" and won't let me just activate my copy of screenflow 3. What the heck, man? Its weird too. When i go to serial number it looks like this It has an "activate" button but when i enter the serial number, the "activate" button changes to "upgrade" What's going on? How can i get my app back without updating to a whole new version?
