Latest version crashes dont buy

I was warned that a certain update would crash so I didnt up date but then another update came and I figured they had to have fixed the problem. Everything was good for a while after updating and then it updated on November 28th 2014... I go to open app and it crashes and brings me back to home screen. I have apps set for the entire month of December and there is no way for me to access. Please get this problem fixed asap s. Can access my appointments...
