Mission Complete: Hard Mode Unlocked

I've seen some interesting things over the years in e-mail. Most of it is spam, so it's not really worth mentioning because its garbage designed to bypass spam filters. But every so often, an actual person's e-mail becomes interesting.

Like this, an e-mail we got at my work fairly recently:

"Actually I got the computer.
but Hard is not working.
So you sent to me new hard.
but I still do get the Hard.
can you check it?

Thanks."

...

...

I don't even begin to understand that. The mind reels.
