That's exactly what I'm doing, didn't I? The problem here is that even before I try to create the file the authentication at the application level fails. As you can see what I'm doing first is to authenticate at the PICC level then I create the new application then I select the new application and then I try to authenticate at the application level but that authentication fails (as you can see I'm using the default application key). Before I create the new file I want to change the application password but the default authentication fails. I would appreciate any help to solve the application authentication problem. Thanks!
