Hi Visc,

The keys in this giveaway that you won - https://www.steamgifts.com/giveaway/7rd3c/rune-knights/search?page=4#Ixecjzd
were revoked, so it appears as an unactivated win on your account. This can cause problems entering some sgtools protected giveaways or may lead people to blacklist you.

If you want to clear this from your account, you could comment on the giveaway and ask the giveaway creator to put in a ticket to remove your win. You can see that a lot of other winners have done this already.
