I didn't go to the AS center and immediately solved it at home, and I'm using tissue to absorb lung ink! It wasn't a waste of money at all! Thanks a lot!

Apart from the first key that I bought that did not arrive, the next 2 keys I bought arrived (I've only used one so far) so I'll save the other one for next time. Thanks very much for your help. Shelley Hamilton.
