This happens in a split second after I run it, and then abruptly it is all closed and I am told the following:
System.MissingMethodException: Method not found: 'Boolean Microsoft.Xna.Framework.Rectangle.Contains(Microsoft.Xna.Framework.Point)'.
at #jd.#qe.#RA(Boolean )
at #jd.#Ed.#Kv()
at #ee.#Re.Update(GameTime )
at Microsoft.Xna.Framework.Game.Run()
at #ee.#de.#5z()
If I restart the program, this just repeats itself, so what is the problem?
