A Continuum account on your other computer? Or an account of something else? If it's a Continuum account, there is no problem is using it on two different computers (just not at the same time, obviously) But make sure you enter the right password And make sure that you are changing the "PLAYER NAME" , not PROFILE NAME. You can have multiple profiles using the same Player name. The profile name doesn't matter at all If you're trying to create a NEW account, as your thread !@#$%^&*le suggests, then make sure the name does not already exists. If it exists, it will tell you that the password is invalid. So you'd better try with a random-ish name first like Purge said. Just don't use special characters at the beginning. Once you get in, you can check for existing names with ?find playername. It will say 'Unknown user.' if the name does not exist, and then you can create it. On a side note, when creating accounts, enter your real e-mail address... It will be useful if you forget your password.
