Hi Alex,
Thanks for your reply.
I have an exam in a couple of months and need to explore all possibilities of PRing to make the maximum effort in trying to improve my skills. Up to now, I have not been able to Activate. I PR the book, even individual chapters (only 6 in total) and I've yet to activate. However, I won't be giving up and PR every day at least 3 times, the last one being just before I retire for the night so that I can 'dream' of activating it!
Thanks,
Maz
