Wont Open

I bought this app a while ago thinking it would be very useful for school. Since I downloaded it I havent been able to open it. Not once. I have reinstalled it 3 times now and the same thing keeps happening. When I try to open it a box pops up and says "iHomework cannot be opened because of a problem". Then when I go to see what I can do to fix the problem they just tell me to uninstall it then go back and reinstall it. It is extremely frustrating and a waste of my time and money.
