ROB RUN Not Loading or Freezing: Official Checks

If ROB RUN will not load or keeps freezing, Kefir recommends checking the internet connection, restarting the game and Steam, updating the graphics driver, and verifying the installed game files.

Work through the checks

1. Check that your internet connection is working.
2. Restart ROB RUN and Steam.
3. Update your graphics driver.
4. In Steam, open the game’s Properties → Installed Files → Verify integrity of game files.

These are general checks for loading and freezing. A specific error code can have a different documented action; see ROB RUN error codes.

If the issue continues

Record the exact message and the step at which the game stops. Kefir’s checks are troubleshooting steps, not a guarantee that every outage or device issue has the same cause. If the problem persists, see how to report a bug.
