Why does a program run in one account but not another?

Question

I am trying to run Prism (from graphpad) on my macbook pro. The application is hosted on a server accessed using an adress beginning with smb:// . I have copied the application shortcut to the dock and am able to run it absolutely fine on one user account. In my other user account, the program starts and goes through an initialization screen, then freezes (colourwheel when the mouse is over the menu bar). This application has run fine for the last 18 months, and has only now developed a problem. I have spoken with our institute's IT professionals, and they have suggested some things, but none have worked. My network connection is stable and, as far as I can, I have repaired all permissions.
Any ideas? I really, really don't want to have to flip between accounts to use this somewhat essential graphing program!
Thanks in advance!

again,
"start debugging by using the following in both functions:
trace(this);  // to check if you're still within scope of your class in both."
