lost computer and all info in house fire ...now what?

If you lose something in a fire, perhaps you can claim for it under your insurance. People think of this for computers, but I don't hear much from people trying it for lost software. (They may just ask why you didn't have a backup; they might also look at the current value of ancient software rather than replacement value). Still, could be worth a try.

You may be able to download it from your Adobe account if you registered it, but it may not run on current Windows operating systems and certainly not on a new Mac.
