Hello!
Unfortunately Valve released a Steam beta client update that broke the DisplayFusion licensing last week. They have fixed the bug and released a new beta client, here is what you need to do to get DisplayFusion working again:
- In your Steam client, click "Steam > Check for Steam Client Updates"
- After restarting Steam, right-click DisplayFusion in your games list and click "Delete Local Content"
- Don't worry, your settings will be saved!
- After DisplayFusion is removed, right-click it again and click "Install"
- After Steam installs DisplayFusion, launch DisplayFusion through Steam
- You must launch DisplayFusion through Steam the first time, NOT the start menu, so that the licensing is setup correctly
If you still have issues with your Steam license please let me know.
Thanks!
