Hello,
In this case, you may try a clean install and make sureyou install the latest version of the program:
Uninstall Voxal, then delete 3 folders named "Voxal" and 1 named "Components" from these locations:
**C:\Users\<username>\AppData\Roaming\NCH Software\Voxal\
**C:\Program Files (x86)\NCH Software\Voxal\
**C:\Program Files (x86)\NCH Software\Components
**C:\ProgramData\NCH Software\Voxal\
**If you can't find any of the folders, just continue.
After that, restart your computer and reinstall the program using this link: https://www.nchsoftware.com/voicechanger/vxlsetup.exe
Once done, restart your system one more time and try again.
If you still have issues, you may need to submit a support ticket: https://www.nch.com.au/support/
