When you pay for your easy1up membersip the payment goes to your sponsor.
Your sponsor then needs to manually activate your membership and this can take up to 24 hours (but usually its much quicker than that...)
If its been 24 hours and you still show "unpaid" in the members area, simply CONTACT YOUR SPONSOR by emailing them.
Their email should show in the members area once you log into your easy1up account.
Simply email them and ask them to activate your membership and send them proof you sent the payment.
Another reason why your membership could show "unpaid" is if you did not complete the admin payment for the level you purchased.
To do so, simply log into your members area in Easy1up and pay the admin fee for the level you purchased, your account should show "paid" after that.
