We are aware of this issue and working towards a fix.
For now, follow this workaround:
- Close the simulator
- Launch ChasePlane
- Enable Release Candidates in the ChasePlane Preferences
- Wait for the green arrow to show up at the top right of the interface (should take less than a minute)
- Click the green arrow
- You should now be updated to the latest version and should no longer experience the issue.
Please open a ticket if you are still having issues.
