I have a region locked key for Dirt Showdown

Not Canada. got the "not available for purchase in your country". Not the normal duplicate key mesg.

Not Egypt

I'm soo curious now xD

Move this to puzzles!

not working in India. Not available in country.

Already used, Not me, but I think it's CN version

Because in China have a online games store (like Green Man Gaming) sell this game, usually lower prices and region locked.

Not Hong Kong

Not bulgaria either

Looks like you got scammed.

Not RU/CIS

no luck in israel xd.

Well maybe Elon Musk starts Mars expedition?? ^^ or guys from Space Station also want have a little fun?

Not avaible in Death Star. Damn rebels!

Does not work in India as well. Thank you though :)

Not from Croatia either..

Not for EU2 (Czech Republic)

CN-key, I'm sure...

It's not available from my bedroom region.
Ill try from the kitchen now.

EDIT: Tried every region of my house, even my neighbour's doghouse with no success. Now I'm confused

Send it to the International Space Station, see if they can get it to work.

Not available in Gensokyo either... damn Lunarians and their region locks!

Jokes aside, looks like we have a solution (here, here, and here), it's most likely a Chinese key, stolen by an ungrateful ninja (or duped from the start).
If someone from China could make a screenshot of the activation popup, it should say something like "duplicated key", instead of "not available".
Don't forget to send a recovery e-mail to scare the ninja (and hopefully, force them to learn gratitude) :3

Not India.

not Brazil
