so i redownloaded steam yesterday bc it wasn’t working (not surprising bc i hadn’t touched it for two years) and i want to play portal, however it wants me to download portal

i do not want to download portal, i already downloaded it like two years ago when i bought it, is there any way i can avoid downloading it again?

error: could not connect to steam network. this could be due to a problem with your internet connection, or with the steam network.

i downloaded steam + portal like two years ago and haven’t touched them since, my internet is fine, why is this happening?
