OneNote 2013 is nonfunctional, anyone else?

Hi I have been using OneNote (Office 365) on my surface pro ever since I bought it last year. This morning I woke up to it crashing a few seconds after I begin the program. Anyone else have this problem? Im concerned. Ive checked for updates and installed them and nothing. I will try uninstalling and re installing soon. Doing this always worries me even though I have everything on my OneDrive, but still. It just says OneNote has stopped working. The message gives the option to click on debug, but whether I do that or not, it still crashes.

thanks in advance
