SGtools pass failed

Log in to SGTools - top left corner - click the arrow next to "Home" - select "Synchronize" from the dropdown menu.
That should solve your problem.

It lists the specific games that it thinks you did not activate. What games is it listing?

just checked your username, try now, SGtools cant find none activated games or multiple wins

if it still doesnt work, try clearing your browser cache

If you have done the sync as others have mentioned, and still have a problem, leave a message in the relevant thread as SG admins are different from the SGTools admin

SGtools doesnt fetch a cached version of your games list when you self-syncronize (like Steamgifts does)

the DEV already knows about this issue for at least a month

ps. https://www.steamgifts.com/go/comment/fEHB5wl

OP you probably have your profile as friends only or private, thats why SGTOOLS doesnt have an UPDATED version your list of games, to fix it you have to leave your profile as public for some hours and then trying again

Thanks to all for help !

as cbones mentioned: if a game causes a problem, ask in the thread for help and they will help you^^
you might also ask the giveaway creator for the link. if you explain the situation to him, he might give it to you.
