I bought the program in Gumroad and I installed it, but I don’t see where is the key or how can I get mine.
You should have received an email just after you bought it.
I have an email from gumroad but there is no key on it. The content of the email is the following, but I can’t see any key. From who I was supposed to get the email with the key?

You should have received a seperate email, not the Gumroad one.
Ok, I will check again. But I didn’t see any. What should I look for? I mean, from what address is sent that email?
I solve it already, thanks.
Hi there,
I also purchased Skatter after seeing it on architizer, but I didn’t get an activation email - only one from gunroad?
Sent an email to support but guess you guys are in a separate time zone - I’m in the UK.

Hi Euan, I replied to your email 
Hi, i just bought skatter and I have the same problem. I didn’t get the serial activation in my email. Please check my case
You should have received your serial in a separate email. Please check your spam folder and remove the email from there, so that your Email Provider knows this is not spam. This is important so that other people don’t get the same issue.
