Why? All kipper expansion work with A500, A1000, A2000, CDTV.
The CF card version work with A2000.

What exactly happens (or doesn't)?
What other expansions do you have in your A2000?
Have you tried the kipper expansion with Zorro cards removed?

Hmmm... just read BBOAH and it says it's just for the A500. It wasn't mis-sold then at least.
