Calling this a Win XP problem may be a strech, but I think I have caused such.

I have used Value Line Mutual Fund Survey successfully for a number of years on my computers, and initially on my laptop using Win XP Pro, but for the past nine months every time I call up a graph I get a dialog labeled bc453rtl.dll, saying, "Floating point: divide by zero." When I hit OK or the red X, the whole program exits. I have talked & written to the Value Line Tech reps, but they are unable to help. The program works fine on a different machine with Win XP Home. I have tried copying both the working folder on the Home machine to the Pro machine (same result), and copying bc453rtl.dll from the Home machine to the Pro machine into C:\Windows\System, the only place I found it (still no change). The earliest Restore Point I have on the Pro machine follows the period of failures, so I can't just recover a working Restore Point. When the program, which was first written for Win 95, installs it alters Win.ini and System.ini, but looking at those files fails to show any reference to the problem dll file.The fact that the program works fine on the Home machine makes me think I have caused this problem and it is in Win XP Pro. My hard drive is 2/3 empty, and the chip is pentium 4. I have 384 MB of RAM. Does any of this suggest a solution?
