Is it activated then? The idea obviously isto stop people using one copy over & over, in my experience, they generally activate it ok, even if there is a question mark, for example if the machine blows up & you drop it into a new one.
All that I've had is the odd decline & then been put through to an indian guy who asks whether I'm using it on more than one machine, then dishes out the numbers when I confirm I'm not. I'm not btw, I'm an honest geek.
