Still Stuck

I am still oblivious to exactly what is wrong with my computer. I've searched all day for "Keygen" shortcuts on the internet, but it's all alien to me. I don't know how much more time to waste on it. I've got deadlines to consider - but how can I got on with them if I can't open Word?
I bet there's a really simple remedy, but I'm too scared to apply anything - just in case I twist myself and my computer into even bigger knots.

I've been using Google Docs the past two days, seemed like a good idea. It simulates word documents online, all you have to do is set up an account. I've got four files so far, I don't know if I fully trust it, but I'll put copies on my memory stick for backup. The greatest benefit I can fathom from it, is that you can access these documents anywhere.

So, if I don't get myself out of this Microsoft deadlock sharpish, at least I've got somewhere to write for now.
