This is amazing. This error code seems to be very common amongst users. I'd imagine Magix would have fixed this by now. Anyway, I registered the program under a different email address than what was used to buy it.
But here is the thing. I researched and found the solution. Log into the magix portal and simply change the email address. Well, I tried that. Under both email addresses, and in both cases, I got the same error message... that the email address I tried to fix it to is already in use.
I'm on the brink of uninstalling this monstrosity and requesting a refund.
So how do I fix this problem?
