First of all, asking 10 times in a row (or however many it was), without waiting for an answer is not at all acceptable. Secondly, if you did input the proper keys as instructed, and it's still not working, say so. Thirdly, if you do not provide us with all the information instead of just saying "it's not working", we will not be able to help because we can't just guess out of the blue as to why it doesn't work. We need more info. So, if it's not working when you enter the new keys, what's happening? What does the screen look like or say? MORE INFO PLEASE!
