very dissapointed

I started playing around with different simulations and all the sudden it froze up on me and I havent been able to do anything with it since. (I have had the program for less than a week and used it for only two days) Something needs to be done wheather it is a full refund or getting the program to work the right way and not be frozen every time I try to open it.
