Write access was not granted

Usually that means that you don't have permission to save there, but could also mean that the drive is formatting in a way that can be read but not written (such as: MacOS can read NTFS, but not write to it).

Boilerplate-text macro:

Before we waste both your time and mine exchanging potentially irrelevant information, would you be so kind to specify whether you are on a Macintosh or a Windows PC?

If you're on a Mac, I may have a suggestion or two; if on Windows, I can't help you at all.

Thanks in advance.

I have a new mac & have downloaded & paid for CC
