Please help! all of a sudden my pages, keynote and numbers wont open and gives me a "problem report!"

I have a 13-inch mid 2010 macbook.. I have OS X Yosemite version 10.10.2 and my processor is 2.4 GHz Intel Core 2 Duo and never had a problem with any of these programs.. Now I just upgraded to this OS X Yosemite today (thinking it would fix the problem with pages not opening up) well it did nothing and still when I tried to open pages, keynote or numbers I get a problem report error saying.....
