My steam installation was having some weird problems, so I "reinstalled" steam by deleting everything EXCEPT:
This caused steam to redownload all its files. On launch I get the login prompt, I type in my authentication details, but when I click
Login, Steam asks to authorize my machine.
My old steam files are still in my trash bin. What is the "authorization file" called? I want to copy it back to my current steam folder. I don't think this action should cause problems since it's the same machine.
