I can't view timing UI in EFDC_Explorer5

The timing adjustment UI is not displayed. I tried to reinstall it, but the same thing happens.
What can i do to fix it?

It is very difficult to say, and could be a result of the version of Windows, or your computer configuration. EE5 is very old and we have not tested it with Windows 10. We would suggest you upgrade to the latest version of EEMS, 10.3, as we have tested that thoroughly with recent releases of Windows.
