3DS Max 2021 - Cant read .mzp script


Hello everyone,

I updated to the latest max 2021 recently and havent been able to install any of the scripts i used to use, im getting an error message:

I cant run them manually, the .mzp script isnt showing up in the browse dialog, only when i switch to *all files, when i do that i get the error message shown above.

I cant drag and drop, i get a circle with a strike going through it, on my cursor when I try and letting go of the button does nothing.

Would be great if someone is familiar with this because I cant find anything on google after doing thorough searches! Thanks!
