Vortex Wars

First when i load the game, a little error window pops up and says

"You can only run one instance of this game on your computer"
Then another one comes up after i press OK on that last note
"Your account has been used on different computer, you have been signed out"

And then it just says "loading" and nothing happens... Help.

1. Make sure you do not have other tabs/browsers running the game.
2. If still happening, try logging in with a guest account for about 5 minutes. Then logout and login with your account.

1. Already done that.
2. Can't even press play as guest thanks to the "loading" thingy
