Created my own account to try the game but no longer works for wife or myself. When the game is started and we enter our login details and click enter it clicks then just sits @ that same screen (no matter how long you wait). esc still brings up the exit dialog so not sure whats up.
It's possible that the an anti-virus is blocking the hook in the client which allows you to connect to our servers. Are you using one and if so can you try it after disabling it? Also what server are you trying to log into? There was a patch for Heroes released today and Heroes being in public beta is not yet online 24/7
