everything is working for me now but first thing i did was logging in with google chrome instead of firefox like Noodle said and the download button was green and was klickable, loggend in with firefox afterwards and there it was too.
thanks noodle for helping

@pajamas do you share games with someone or get shared games from someone who owns the game too? was thinking that this could be messing with something

i saw a post where you said to someone its maybe problem with his permissions that he cant upload and stuff could it be a problem with this?

nothing changed for me still cant klick the download button also changed my profile settings to private and back to see if it does anything, nothing.

like the title says i cant download anything, relogged multiple times nothing happens. i own the game with addon.
edit: profile is not private
