Refresh Your Steam Files
I believe that Steam's files may be modified, corrupted, missing, or misconfigured. How can I restore Steam to its original state without having to reinstall my games?
Why you may need to refresh your Steam files

Refreshing your Steam files can resolve many issues that can be encountered in the Steam application, store, or games. Performing this operation will ensure that there are no issues that could be resolved with a new installation of Steam, and is a good place to start any troubleshooting process.

Note:
This process will not affect your currently installed games.

Windows XP/Vista/7

Completely exit the Steam client.
Open the run dialogue by pressing windows key + r (you can also navigate here from the start menu by typing run).
Type steam://flushconfig then press enter. (If asked to allow this website to open a program, please click Allow or OK).
Restart your computer.
Now, launch Steam directly from the installation folder, not from a pre-existing shortcut (~C:\program files (x86)\Steam).
The Steam application will either appear as Steam or Steam.exe depending on whether your settings show file extensions.

Mac OSX

Completely exit the Steam client.
Open Safari and type steam://flushconfig then press enter
Restart your computer.
Launch Steam and re-test the issue.

Linux

Open Terminal
Type steam --reset
You will see the following: Installing bootstrap /home/[username]/.steam/steam/bootstrap.tar.xz
Reset complete!
Restart your computer.
This should remove and download new Steam files for your Steam client.
Launch Steam and re-test the issue.

^ You are the best,ty bro

Half-Life 3 Confirmed.

didn't fix the issue for me. anyone else could get it working?

thanks agent 47 this fixed the problem for me too

I had this problem last night, and the above fix didn't work for me. I fixed it after trying a few different things so I don't know which one actually worked, haha. But anyways:

Step 1) Copied the Dota 2 folder out of steamapps and deleted the original.
Step 2) Logged into my computer with a friends steam account (they own Dota 2, not sure if that matters).
Step 3) Logged into my friends computer with my steam account and started Dota 2.
Step 4) Logged back into my own computer with my steam account.

At this point Dota 2 was back with its rightful name! Then I just copied the files back into the steamapps folder.

Hope this helped!

Edit: From what I've just read on the steam forums it looks like it was Step 2 that fixed it.
