my steam doesn't work, AT ALL. i bought a gift card and i bought some games and none of the games worked, then i tried requesting a refund multiple times and i never got my refund back, then i downloaded skate and when it opened it said to install an anti-cheat and when i did that and even reset the app, it told me to reinstall it, then i do it, restart the game, start the game, and it keeps telling me the same thing over and over again. what do i do?
