I can't create a giveaway for "Nyctophobia"

I' ve got a key for this game, but when I try to create the giveaway, the game isn't "found" by SG... What Can I Do?

Because it was for free. You can't create giveaway for games, which was free.

This was given away for free which means you can't create a ga for it.

always this threads again

Working as intended.

Ok, i didn't know that. It's not a free game on steam, I thought I could do it.
