IF you lost your maFiles OR lost your encryption key, go here and click "Remove Authenticator" then enter your revocation code that you wrote down when you first added your account to SDA.

If you didn't follow the instructions and write down your revocation code, you really screwed up. The only option is beg to Steam Support and say you lost your mobile authenticator and revocation code.
