In the upper right of the launcher screen should be whatever account name the launcher remembers you as with a little down arrow next to it and then the option to log out. If you click the little down arrow and look next to the account name there is a small x. Click the x and the launcher will forget that account log in information. If you have more than one account being remembered by the launcher on that computer click the x for each account you want the launcher to forget. When you next log in do not check the box next to 'remember me on this computer' and it shouldn't keep track of that log in information any more.
Thanks; that did it.
Having finally tried DCUO, I have to agree: it's hard for this 55-year-old, who played CoX for years, to replace it with a console game. The keymapping is all wrong, and would be a bear to fix; I don't know that there even IS a way to set it up so that I can turn with keypresses, while using the mouse to interact and fire powers. (I was able to set up Guild Wars' and CO's controls very much like I had CoX's - the keyboard for movement, and the mouse for clicking what's on the screen). And in CoX, I mainly soloed, and could immerse myself in skulking through mission maps, sneaking up on groups of opponents, and planning tactics. DCUO feels more like an over-caffeinated, scream-and-leap style of play is required, and I'm just not Leeroy Jenkins. Plus, all of the "special effects", during battle, make it hard to tell how the fight's progressing, so that I can decide my next move.
I'm just not sure how much this old dog can adapt to this sort of thing.
Can we go home now?
