When I start LRTimeLapse and check the license, my old email displays. How do I go about updating the email?

Thanks.

You can't change it there (it's only for display, won't be actually used).
When you buy the next upgrade (like for LRT 7), just use your new email and I'll assign it. Then you'd also get a new license with your new email on it. You can send me an email with your old and new email if you want, then I'll change it in my database.
