Check your browser history. Did you pay for your Pro from LLC ... make sure it was the official LW site !

After all, if you did buy Pro from the official site, you'd have been sent an email with a link to your personal Pro download page (which you should always bookmark.) Check your email.

How much did you pay for Pro?
