Hello,
Sorry to hear you are having issues. You should be able to open up Start10 Configuration panel via Window10 start menu -> Startdock->Start10.

From there check if you have select "Windows 7 Style" on "Which style of Start menu would you prefer?" and on "Control" section.

What should happen when you are on the desktop part , select "Start button shows Start menu" on the first drop down menu option.

Please try purge and reinstall steps as mentioned here: https://forums.stardock.com/486022/start10-support-faq#reinstalling Just make sure to redownload the latest version from your account. Reboot after the purged. Reinstall, and Reboot again after the installation. Retest it. Report back here.

Thank you,
