I have some questions about your first post. You've written the text below:
I used to have few years ago a Multibit Classic bitcoin wallet in a computer that then stop working. I tried to delete some programmes to makes some space as it was only 2GB memory and was full, but I think that I did damage even further and this computer does not work anymore. In addition, the screen is black even when plugged in and switched on (I thing the hardware is damaged too) I used to have one bitcoin there.
3 years ago, I bought another laptop (with 4 GB memory). I downloaded the Multibit wallet and it's the 0.5.18 classic version. I cannot see any bitcoin on the balance. It's show 0 BTC.
1) On your first computer, do you remember what exactly you deleted? I know that it's been years, but you may remember something important. Was your deletion for example the cause of your computer's crash?
2) You say that you had a bitcoin there, on your first pc. Are you completely sure that you had used Multibit Classic to receive that one bitcoin? For example, do you remember generating an address or an invoice for your receival? I've written you on my first reply how an address looks like. (1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa).
3) After 3 years, once you bought the new laptop and installed Multibit classic again, what did you do to after the installation? How did you expect to show you a balance since you hadn't imported the old wallet?
4) Is there anyone else besides Jim Burton that knows about this? A known/friend of yours that bought 1 bitcoin back then, in that meeting?
Please correct me if I'm somewhere wrong: You bought one bitcoin in a meeting some years ago. The tech-guy who introduced you bitcoin, told you to use Multibit Classic and sent you that bitcoin to your wallet. Later, he insisted that you have to be careful and write these 16 words, because you could recover your bitcoin this way if your computer ever stopped working. He never told you how to recover it, did he?
Nicky, it seems that these 16 words were generated by blockchain.info. I can confirm what HCP said. Here's a link for you to read:

From a bitcointalk googling, I found out about this forgot-password link, I think that this is what you're looking for:
