I didn't create the file. I'm trying to read the contents of an existing application.
Are there specific file permissions I should be checking for, or parameters that might cause the error I'm seeing?
The file type shows as DataStandard, MACed communication mode, and I'm authenticating with the key number indicated by getFileSettings().getReadAccess().
