Teleski,
Sorry to hear about your experience. I can tell you that my spell checker does not function that way. For one thing, the "Add" button is functional. For another, I believe that when I upgraded I kept the old terms (and names) that I had previously added - I might be wrong about that, but I believe it to be the case. I think there is some sort of bug in your spell checker- I would encourage you to contact AC support and ask them about it. Start with the non-functional "Add" button...
