Trying to run two instances of Origin with Aster and Sandboxie

Am I doing this correctly? Every time I run Origin .exe with Sandboxie and login, then launch the game on either account from the two running instances of windows, I'm hit with a message box from EA saying -- "We're sorry. an error has occurred" --"We are unable to connect to EA servers yo activate Dead Space 3 on this computer using your account" -- What does that mean? are there files that I need to copy that are possibly left to do in order to bypass this error message and play the games from both accounts. - Yes I bought the game twice in order to make them run from two different accounts so I don't know what else I am missing here. Any help would be greatly appreciated.
