Yes, skwire, I understand that this COULD be taken as a keygen, and I completely understand your trepidation. I can assure you that, in my case, it is not. I work at a computer shop, and a customer brought us a laptop that had obviously been well used and the key sticker on the bottom is pretty worn. There was no way to fix the laptop, except by re-formatting, and now I am left in a not so good situation.
I can clearly read some of the characters and others are not so legible, but I can guess at them (there are probably 5-7 out of the 25 characters that are less than readable).
It is my plan that I will have to take a chunk out of my days and try the possible combinations (which I understand could be quite numerous) to see if I can help this customer out.
I started to write a list out of the possible combinations, but that got very cumbersome very quickly.
