I'm having problems running a program that I need for one of my courses. The program worked fine until today. The program doesn't need to be installed, you just open it from the cd and then pick which video you want to view. The program seems to open fine, but when you select a video, the video screen just shows a big red x. The only advice the readme file for the program has is to make sure Quicktime is version 3 or better. I tried to open the Quicktime player to see if it was working alright and got this message:
Microsoft Visual C++ Runtime Library
Buffer overrun detected!
Program C:\PROGRAM FILES\INTERNET EXPLORER\IEXPLORE.EXE
A buffer overrun has been detected which has corrupted the programs internal state.
The program cannot safely continue execution and must now be terminated."
I would really appreciate it if someone could help me out, I really need to be able to access this program, it's required for my class

Thanks,
Erin
