From what I know trial and full version is the same, just trial have limited time. Please try the cleanboot steps as mentioned here : https://forums.stardock.com/486022/start10-support-faq#cleanboot to see if there is any conflicting application with Start10
And, please check your system, try this :
-For Win10 Users: Open the Start Screen, and type 'cmd'. Right-click on the search result and select 'Run as administrator' from below.
-Type: sfc /scannow
-Wait for the scan to complete (this can take several minutes)

If the SFC finds errors, but cannot fix them, please also run the following command in the same command prompt window:
dism.exe /online /Cleanup-Image /RestoreHealth

The above command should assist with replacing any damaged or problematic system files. Please note, however, since it may require restoring certain files, this process can take some time and you will need to be patient until it has completed. Please let me know whether this resolves your problem or if you have any additional questions.
