I have downloaded the free version tested it out and then paid the ezCheckPersonal annual fee but when I did that, the program no longer loads. It shows up in the Dock but can't be found on any of the windows. I am using an iMac 2021M1 Chip, 16gb with BigSur OS. I've tried uninstalling the program and reinstalling it by downloading it from the App Store. I have tried all day to get it to run, but to no avail. HELP!
