It has happened before, but it was very wide spread after Steam Update messed up something on a lot of computers.
This time, I don't see the complaints, although I see a few people who can no longer log in. I did everything, should just wait and hope Steam/Valve fixes this?
Around that time, Valve began negotiating contracts with several publishers and independent developers to release their products, including Rag Doll Kung Fu and Darwinia, on Steam.
Steam provides the user with installation and automatic updating of games, and community features such as friends lists and groups, cloud saving, and in-game voice and chat functionality.The software provides a freely available application programming interface (API) called Steamworks, which developers can use to integrate many of Steam's functions into their products, including networking, matchmaking, in-game achievements, micro-transactions, and support for user-created content through Steam Workshop.Though initially developed for use on Microsoft Windows operating systems, versions for OS X and Linux were later released.So as a last resort, I uninstalled Steam completely along with every game I had in the library.I used CCleaner to clean out the registry and all that after.
