Problem with Steam

Everytime i try to start football manager through Steam it says "this game is currently unavailable. Please try again at another time." I've never had this problem before but its been like this since yesterday.

Hope somebody could shed some light on this, thanks.

I got his from the steam support website. Try this:

After each step, please re-test the issue.

1. Exit and restart Steam
   
2. Update All Drivers - including DirectX, PhysX, and Visual C++ as found at the bottom of the guide
   
3. Exit Steam and rename the ClientRegistry.blob and restart Steam
   
4. Exit Steam and delete everything under the Steam installation directory except Steam.exe, the ClientRegistryOld.blob, and the \SteamApps folder - this will force Steam to update when you log in
   
5. Complete the Verifying GCF Cache Files process to repair your game cache files.
   
6. This error may be caused by having certain Steam files set to Read Only. To resolve this:
   
7. Exit Steam.
   
8. Navigate to the directory where you have installed Steam. (Typically C:\Program Files\ or C:\Program Files\Valve\.)
   
9. Right-click on the Steam folder.
   
10. Select Properties.
    
11. Check the Read-Only checkbox and press Apply.
    
12. Uncheck the Read-Only checkbox and press Apply.
    
13. If this issue is only happening on a third party non-Valve game, please try launching the game's .exe directly from its installation folder: C:\Program Files\Steam\SteamApps\Common\<Game Title>. You may also try other .exe's such as Launcher.exe in the game folder to see if a different error message is found.
    
14. If the issue persists, it may be caused by a network configuration issue. Please complete the Troubleshooting Network Connectivity guide to further assess the problem.
