First, yes, I have followed the instructions under #11 How To Import Data on the add-on page and, yes, I have posted a question on the forum on ESOUI but have had no response from the add-on author. I am posting here because I use a mac and this seems to be a Terminal-related issue.
I updated to 3.13.15b. Prior to that I could import / export data using the .command file with no problem at all.
Now when I run DownloadNewData.command I get a message saying that I do not have appropriate access privileges to execute the file. Does anyone have any idea if there is anything else I could try to get this to work?
