It's just a thought but what if!
The reason that VM start the key rolls coincides with one of their employees, who happen to be an expert on coding.
They tell them that with Christmas approaching and the new codeing system that he has come up with if, released!.
Would send a panic wave though out the population with an illegal box.
This may result in some new customer activity as not to miss out and spoil Christmas.
This expert in coding could then release a fix within a couple of days for a small fee of course and make a tidy packet for themselves.
Might be a bit controversial, what do you think?
