Can you copy it from the CD and put it where it goes? Or did you download it from the internet? I had trouble with Norton this time around and I had to contact their tech support and they emailed me some fixes. Also, I had to manually create a couple of .dll files. I just had to create them in notepad, use the correct name, save as a .dll and it worked.

If your equation requires either a complex combination of variables to get the desired result OR you can't seem to get the result regardless of the variables....it ain't your variables, it's your constant.
