YouTube Account Authorization Script Errors

[g0mgx]

I have v3.81 of VideoPad running on Win10 and have been using successfully for some time. I recently rebuilt my PC and cannot complete the YouTube account Authorization.

I get "an error has occurred in the script on this page" and then eventually when I get to the final screen, the "allow" button is not functional.

I don't know how to get round this (except creating a video file and uploading manually which is a pain).

Any pointers appreciated, some images linked below:

Error 1

Error 2

Broken Allow Button

Thanks
