If you want to make a change to your account, you can manage most Stardock account issues (including changing your password, resetting your password if you forgot it, and moving products from one account to another) at http://www.stardock.com/support/ in the "Account Tools" section. 

Indeed.

As a side note, this will NOT affect your Impulse account.  That's a separate thing, now, so you'll need to contact downloadsupport@gamestop.com for that.
