Fireworks CS6-Not part of Creative Cloud but blocking me.

I have CS6 version of Fireworks. I used to have Creative Cloud but had to cancel (Laid off). Fireworks was not updated or upgraded to CC. It was an earlier program which I kept without an ugrade to Cloud. Now I can't open Fireworks CS6 even though it was never part of my CC package. I had already purchased as a stand alone way before Creative Cloud. Now, of course it's like the money I paid fpor it is down the drain. What can I do to get it back for use?
