Don't starve togheter bug / just bought the game

Hi,

I really want to play the game that I bought for just some days ago but it dosen't work. My other games on Steam does work but not this... I have done theese steps. Can someone please help me?
 

1) Run the Steam client as an Administrator
- Fully close out of Steam and restart your computer.
- After restarting your computer, right-click on the Steam icon > select "Run as Administrator"
- If that does not work, go to step #2.

2) Run Don't Starve Together as an Administrator
- Run Don't Starve Together dontstarve_steam.exe as an administrator in your game folders (Steam\steamapps\common\Don't Starve Together\bin\dontstarve_steam.exe)
- Right-click on it and select "Run as Administrator"

If Steps #1 and Step #2 do not help with the issue, try Step #3 and these should be able to help resolve the issue.

3) Check your Anti-virus, anti-malware, Firewall, and security settings
- Depending on your firewall, security, and antivirus settings, occasionally it may block a program that you want to access. Ensure that your firewall, security settings, and other antivirus software is allowing the game to do so. You can find more information here: https://support.steampowered.com/kb_article.php?ref=9828-SFLZ-9289

And if all fails, If that fails, try creating another save directory (say c:\DontStarveTogether) and then launch the game with that as the save directory:

- In steam right-click the game in your library
- Select ‘properties’
- Click ‘Set launch options’
- Enter ‘-persistent_storage_root c:\DontStarveTogether’ (without the quotes)
- Close dialog.
- And the next one
- Launch the game.
