Welcome screen loaded in the top left-hand corner of my desktop

When I start Captivate 2017 (10.0.0.192) the startup screen appears in the display's upper, left-hand corner.
When I select a project, the startup screen disappears. The Captivate menu is still visible, but the user interface disappears.
Things I have tried so far:
- Restart
- Running utility for cleaning preferences (CleanPreferencesMac [Applications > Adobe > Adobe Captivate 2017 > utils])
- Adjusting the resolution of the screen
- Zooming in/out
- Reinstalling the entire program more than one time
Does anyone have any idea or suggestion I can do for solving this issue ?
I'd appreciate your time for helping me.
Thanks,
Marcos
