I tried downpatch my game, I´ve got the 611616 rev.
This revision dosn´t comes with the current of the downpatch, so I used de most current revision of the downpatch to try downgrade, first I haved to download Donet SDK from Google (external link), to start the downpatch, then I started to downpatch, put my verification code, and all right, but in one moment the downpacher gives me a stupid message I don´t understand:
"Downloading depot manifest...Got CDN auth token for steamcontent.com result: Fail (expires 01/01/1970 0:00:00)", after this shows me in the next line "Disconnected from Steam", I don´t understand nothing, Have it relatinship with the born date or what?, Thanks for help me, and sorry if my english isn´t very well.

Thanks you for help me, but the fail still appears I have post a issue in GitHub to try them upgrade the Downpatch because I think what that is necesary
