I really want to upgrade to 4.18, but when I enter my email addy, it says it's not in their files. I've tried the only three emails I've had in the past 10 years, and it still says no. I've been using Pro since earlier this year, and would hate to downgrade just because of a stupid email addy. Is there any way to send my purchase information BACK to the email I registered with... something, ANYTHING that would remind me which address I used?
