So, after trying out a few different characters I decided that I prefer Dark over Light.  However, since I selected Light Pantheon while still a noob trying things out I realized that I would have to create a new Impulse account to be able to play as Dark characters.  However, I am unable to login under this new account.  Instead I just get an invalid user name/password error. 

I bought the game online - do I need to reactivate or something in order to be able to play as Dark??  Please help!

Please tell me this is not intended by the way - if Stardock decided that only half the game will be available to me online now after making a binding decision while still learning how to play the game I am going to be extremely upset. This is already incredibly frustrating.
