I'm not having any luck migrating my DropBox files to Box with the Shuttle.  I want to try a different DropBox Account but every time I click on the DropBox source, it logs me in with the existing creds and doesn't provide an option for a different account.  I've deleted the source and tries to re-add it.  But it just keep authenticating the same DropBox account.  Is there a way to dump those creds and use new ones?

Thanks,
Chris
