All I can say is that one of the main reasons I upgraded to BIAB 2015 for mac (from 2010.5 version) was to able to use the iPad app. So far it's been a complete bust as I have been unable to successfully download song and rendered sound files to my iPad. It all seems to work--until I try to open the file in the application at which point I discover that it's just not there. When I try to re-download the files I get the message that it already exists and do I want to overwrite the files. So I overwrite the files. Then when I select the folder to which I saved them, nothing shows up. I'm beginning to wonder if I wasted my money on this upgrade.
