I just realized something: Only two of the computers in my house are Adobe-authorized, which means I had only six devices registered even if you count the extra eDGe registration. I think an old computer where I used to work may still be occupying at least one of those registrations. Good think they're still around and I know people there. I can have them go to my old computer and deauthorize it.

Good thing to remember: When you ditch or switch a computer, make sure to deauthorize your Adobe ID before you sell it or toss it in the recycling heap.
