It sounds like the original developer made a modification to a standard VI and saved it to a new location without renaming it. Now, when you load it, it pulls the unmodified VI from your local installation because it can't find the modified one. Do you have access to the original developer's computer? You should take note of the warning message. It should tell you where it expected to find the VI. What is the name of the VI? That information would be helpful as well though if you can't find the modified one, you may have some problems trying to recreate it. You could also post your program. Do a Save with Options and select Development Distribution in order to create an llb with the main VI and all subVIs.
