OK, so, this is what I HAVE to do, because of how this site works, I HAVE to create a new account every time I get 'Invalid Token' when attempting to sign in, and from what I've read about this problem, it's connected to how concrete5 software interacts with this website, so I found it's a lot better to NOT connect my Concrete5 setup to this site to avoid any 'Invalid Token' problems this preventing me from logging in to this site, and for testing purposes only, I installed Concrete5 on a WAMP server that doesn't use a FQDN, and if I'm satisfied with how it operates, and the ease of it's use, then I can install it on a real hosting provider.

But right now, I'm having to keep creating new accounts on this site until the 'Invalid Token' problem has been fixed.
