I wanted to upgrade to Master, since I do mostly work on a MAC now. I already have a valid MC 20 license on a Windows machine, that I currently cannot access. I wanted to use the chance to get the special upgrade offer to Master, but there seems no way to do so without having access to my Windows machine, right? If I download and install V20 on my MAC (right here from the board, the latest version), it says Trial Period expired (why that?) and offers to send an extension code. But when I asked for one and entered it, V20 splash screen on my MAC closed, and when I reopened it, it still said Trial Period expired and there's no way to start the program anymore. The purchase link leads to the 44$-version...
So right now, I am completely stuck.
Any suggestions, what to do?
