>the latest version is v5.0.6. Is this the version you have?>

Thx for asking . . . support got in touch w/me and asked me to set up a Guest Account (which I already had) to login to. It worked!

I was having some other issues and initialize my HD and reinstalled iReal Pro and it works like a champ!

The iReal Pro people couldn't have been more helpful including telling me what to Trash and along w/Terminal command and a new download, all unnecessary in the end but greatly appreciated.

I will give them a glowing review in App Store! Thank you also for checking in :-)
