Common Problems

  • I cannot use the Map Editor for Starcraft 2.
  • The region is showing as XX-07 when I start the game.
  • Error: Game client version mismatch with selected region. You may be able to continue playing if you exit the client, patch from the launcher, and restart.
  • Error: Unable to connect with Blizzard services

If you receive the error "Game client version mismatch with selected region," or if the region displays "XX-07" after game is launched, try the following troubleshooting steps:

  1. Switch to the Beta version of the application
    1. Click on the Blizzard logo at the top-left corner of the App
    2. Choose Settings
    3. Choose Beta
    4. Click on Switch to Beta
      • Note: If you are already using Beta, try switching to the Standard version of the application. Choose Switch to Standard Version instead of Switch to Beta
  2. Delete the PTR executable
    1. Go to the StarCraft II tab in the Blizzard Desktop App
    2. Click Options ⚙
    3. Choose Show in Explorer
    4. In the Starcraft II folder, delete the StarCraft II Public Test(.exe) file
      • Note: If you do not have the Public Test file in the StarCraft II folder, check to see if you have the PTR installed and delete the Public Test file there instead
    5. Launch StarCraft II again
  3. Reinstall StarCraft II
