When I click the confirmation email, why do I get an "Invalid Activation Code" error?

This issue can occur if you resend a confirmation email, then click on one that was previously sent to you. Once we send a new confirmation email, all previous confirmation links are invalid.

Try clicking on the most recent confirmation email. And if you re-send, please wait a few minutes and confirm you are clicking on the most recent confirmation email generated and sent by dlvr.it
