"invalid email" when attempting to activate Curtains
I'm attempting to activate Curtains. I had it previously installed on this computer, but swapped in WindowBlinds for a while (just un-installed that).
I get and "invalid email" error when I try to use the product key. I have 2 keys, each with 5 seats. I checked the activations on the website, one has a single activation, the other has none. I copy-pasted both the email address and the product key.
