currently has a bug

I bought this app to oragnize long-term projects with tasks and subtasks. I dont know if I can do that yet, because I am unable to create even one task without a due date. They provide a button in the date section ("None"), but clicking it crashes the spp.

Hoping for a fix. Fails on IOS 6 and 6.0.1.
