I've written a LOT of apps using VMP over the years.
Your best bet is going to get a hold of the tutorial - that you can download for free. If you were not supplied with the VMP product with the source code you might want to consider getting a copy of it.
Does this app have a name? Guess it's possible you've inherited one of my old ones....
