I cannot run either of the simulation programs on Blackboard. I tried the DOS version, but I don't know how to use it and when it is in use, I cannot see the rest of my programs to know what I am supposed to do. Is there anything else I can do? Could the program run on another computer or is the file the problem? " ""

Which specific simulation programs did you try to run? What error message did you get in each case?

Some students report having trouble running the simulation programs, though most have no trouble at all. You should probably try a different computer, but give me all the details you are encountering here.
