I downloaded visual studio 2013 and added xna to it so that I can run a game I made in vs2010. However I am having an issue in which it is not allowing me to start debugging or start without debugging. The xna I downloaded is from here https://mxa.codeplex.com/releases/view/117230 if anyone can help me I would appreciate it. I can also put the game up, it's just the begining of space invaders I made in college. I forgot to save the completed file so decided to play around with it now I have some free time.
