Hello,
In that case you might want to try a clean installation of the program, first uninstall the program from the PC then go to the locations on your C drive below and make sure you delete all folders of mixpad that you find:
- C:\Program Files (x86)\NCH Software\
- C:\ProgramData\NCH Software\
- C:\Users\<your username>\AppData\Roaming\NCH Software\
(if you can't find the ProgramData or AppData folders, set Windows to show hidden files and folders as per https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files)
Once you are sure you have deleted the MixPad folders from the location I shared above reboot your PC and as soon as it comes back on install the program again and see how it goes.
If this does not help I would recommend you contact the NCH Support team and see if they have anything else you can try, you can create a support ticket for them through the link below:

Good Luck!
