Can't Load UMIK Calibration File

I'm new, so this is likely my mistake. I'm running REW V5.31.3 on a 2020 Mac Mini with M1 processor and Ventura 13.5.2. REW recognizes the UMIK 1, SN 704-1014 and asks if I have a cal file to which I answer yes. The cal file is 7041014_90deg.txt and is on the desktop. A REW Calibration Data window appears and I click on the blue folder icon. A new window appears. I set "Look In: to "Desktop" and enter "7041014_90deg.txt" as the file name and click "Open". Then I get the following:



I have been all thru the REW "Soundcard" and "Cal Files" Preferences to find what I am doing wrong, but I can't figure it out.

It seems like it worked a few months ago, then the original Cal File was deleted. The Cal File mentioned above is a new download from MiniDSP. Could that be part of the problem?

Thanks!

The REW app probably doesn't have permission to access the files, check your privacy settings.

Thanks - that's it!, I need get smarter!
