Crash

OK, I was fiddling around with HWA and suddenly the game crashed while I was running it. The crash window said"Multimedia Fusion Editor Runtime has encountered a problem and needs to close. We are sorry for the inconvenience." .My game just lets you spin an object at certain speeds and resize it. I figured out that every time I set the x scale of my object to something over 5 and then tried to change the y scale, it crashed.
Can anyone help?

A similar message also appeared when I tried to run a exe that someone had posted.
