MK:KE

Where at? Most websites will fix an issue like that if you mail their support.

Never heard of them. You should stick to well known sites to avoid problems.

Anyway, contact them and see if they do anything.

Print(it is in portuguese but is says dup)

Go back to the store and tell them to give you another product.

Never heard of MK:CE Anyone remember WinCE?

I wonder if either are similar to MKKE :-)

Aw, that stinks.
Hopefully, the site is legit and they'll give you another key if you show them your problem with proof.
