Why do I get "Invalid API License Key" when I try to activate my license?

You should first check that you entered your license key and email exactly as they appear on your account.

If you did enter the right license details - and did not accidentally swap key and email - but you're still getting an error message saying "Invalid API License Key...", you should check if the email address assigned to your account matches your license email address.
