Wendell,
Just a few things from the other point of view. And, I certainly agree that support can sometimes be the best way to go. But, wow, we would have to take the entire userboard down if we were going to go with support vs userboards. Everyone on the board knows this is an As Is.
I have steered many people toward paying an IT consultant as I could tell by his or her questions that they needed to go that route.
It sounds as though they did connect to V4. An .xml file is an .xml file (I will go into more detail later if I have time).
But, the code Paul showed is the code in the .xml file and as long as you have the correct path, and the default is the path to the C:\Program Files\Amazing Charts\AmazingCharts.mdf, you should be fine.
The download above can be used on the main computer if for whatever reason the .xml file is gone. Again the path must be correct.
