DONT BUY THE UPGRADE

I loved this app... so much so that I paid for the full upgrade, which then rendered the app useless. Running iOS 9.0.2 on an iPad Mini. Uninstalled and reinstalled the app, did a restore, but the app still wont open at all. Questions to the dev via their site, FB, and Twitter are going unanswered. Dont upgrade until the dev releases a bug fix.
