Sounds to me like most likely you're not allowing cookies for Armorgames.com. You need to do so for the site to "remember" you, i.e., to reognize that you are in fact logged in.
After allowing it, it may help to refresh page, and/or to flush your browser cache, or to fully close browser, then start it up again and log in again.
(So what's a cookie? Try https://en.wikipedia.org/wiki/HTTP_cookie . Essentially, it's a small file that lets your machine communicate with a site's server and vice versa, in order for you to be recognized as that identity, indeed. It is needed in all instances where you need to log in; or if it isn't, skip that site, as it suffers from bad or rather no security. Conversely, you may or may not want to control cookies for sites that don't need them, as they pose potential security issues, no matter how minor. More control and so security does always mean more stuff to fiddle around with and to understand, though. Take it just as far as you want and can manage. There's tons of users allowing all cookies and no great grief seems to usually come to them.
And so now how to allow or disallow them? Depends on your operating system. In Internet Explorer 8, it's under >Extra >Internet options >Privacy; in Firefox 22 and several previous versions, under >Tools >Options >Privacy.)
Even though you are currently logged in here in AG, Still you have to login again to the game since it doesn't automatically work that way like how FB does it by letting you remain logged in for a very long time.
