I’m not sure, during the transition, when we will be addressing the transfer of user accounts to the new website.

You CAN start another user account on the new website using the exact same email as your account on the old website and when we transition everything over from the original site, your original downloads, resources, etc. will seamlessly go into your new account.  Be SURE to use the same email address or this will not work.

And I’m sorry too say it’ll take weeks to transition, because the site is HUGE (over 5000 pages) and we are needing to rebuild everything from scratch.

If you never ordered from the original website, then the new website should have generated a user-account for you when you made your order, and sent you your account details.  If not, you can make an account (register) using the email address you used to order your product, and we’ll attach your order(s) to your account.
