Adobe licenses are for one user and two computers that are not used simultaneously, so you can still use the second activation.
In happier times, I would have advised you to contact Adobe customer support to have them deactivate the other computer, but the outsourced support folks in India have been utterly useless even in this regard lately.
Unfortunately, only Adobe customer service could assist you with your issue in the past. These are user forums; you are not addressing Adobe here.
