Faulty upgrade

Siddur is generally one of our most highly rated apps because of its functionality and many features.
This upgrade has broken siddur which now crashes on startup.
iOS 8.2.1 on iPhone 5

I have updated the comment above in light of the quick fix Rusty Brick made. App is now back to 5-star value. Customer service is highly responsive.
You will not be disappointed with this product if you need a time-contextual siddur, zemanim resource, minyan data base and mizrach finder when you are traveling
