Can't sign into my photoshop account

tried to sign in via my Google account instead of my Photoshop account and wound up signing up for a 7 day free trial. I don't see anyway of switching back to my bought and paid for Photoshop account.

Someone else had this problem last year and their solution was to sign out via their Bridge account and then sign back in...my problem is I don't use Bridge; any suggestions will be GRATEFULLY appreciated. (I'm away from home working on my laptop instead of my desktop machine which signs me in no problem.)
