There's a three accounts registered per IP limit. The IP you're trying to register from is already associated with three or more registered accounts.
Try any of the following:
Google how to reset your modem/router's IP (/release /renew).
Register from a mobile device like a phone or tablet.
Register from another computer, like a friend's, coworker's, or from work or a public place like a library.
Register using a VPN program/service.
