Crashes after In-App Purchase: FIXED

EDIT #2: The issue has finally been fixed! This app is now, once again, the best fully functional calculator you can buy in the App Store!

EDIT: I should mention I'm on the new iPad Mini with Retina Display. After the Nov 14, 2013 update, the app still crashes on opening. I loved this app before on my old iPad, please fix!

I a running iOS 7.0.3, and after purchasing the $9.99 complete pack, the app refuses to open. I thought with all the good reviews, I had found a good all purpose calculator, but instead I'm disappointed.

Please fix!

Lots of capabilities in one app

While some consider $10 for a bit expensive for an app, it's really a great value. I'll be deleting several other apps that this one will nicely replace.

For historical perspective, in 1971 I paid $280 for a calculator the size of a brick that added subtracted multiplied and divided and have one memory. In 1972, my friend paid $395 ($2,200 in 2013$) for HP 35 scientific calculator. It's hard to believe how things of changed.

Great features

This app has what I wanted - easy to read numbers and function keys plus the ability to double check the "tape" of recently entered lists if numbers.
