Okay so I really wanted to ask this on support.steam's site but unfortunately no matter how many times i click resend and make new accounts and use different email addresses, steam refuses to send me a verification email so I can't use that. So for the past few months my steam has been completely unable to download files for valve games like CSS, CSGO, Garry's mod, portal 2, DOD, (ALL valve games, steam will still properly download games, but will not download from ingame) like I enter a server and it says it's downloading textures then suddenly says "missing map [map name]" and doesn't even attempt to download it. I have tried what people have said, to mess with browser firewall settings (even internet explorer), I deleted everything from inside the steam folder except for steam.exe and steamapps, still didn't work, then just said fuck it, deleted EVERYTHING and reinstalled steam, still won't download. I tried doing the sv_downloads, cl_downloads ects stuff, my multiplayer option is checked to download stuff. Even when I go online to manually download the map, the character models and custom textures do not download and all I see are errors, so even if i wanted to manually download the map everytime, it's still near unplayable. I started to think it may have been because I was on Windows 10 but I looked up different comments and people have said it works find with W10 so I have no idea what to do. How can this problem endure through everything I have done? I have tried everything google has to offer in search, nothing works.
