I'm using the 14.5 demo version of .net tools in vs2005 / .net 2 / C#

I noticed in the CSMainDemo example, there is an autocropcommand implemented that I would like to make use of.  I've written a simple app that scans an image, on the acquirepage trigger I am attempting to first pass the image through the autocropcommand and then save it out.  When the autocropcommand runs, I get an exception as follows.  I am almost certain that I am not referencing something properly, but for the life of me I can't figure out what it needs to be or what needs to be set in code for this to work.  Can anyone point me in the right direction?

Thanks in advance!

private AutoCropCommand command;

...

try{

command = new AutoCropCommand(20);

command.Run(image);

}

catch (Exception ex){

MessageBox.Show(ex.ToString());

}

Try the attached application. If this fails as well, there may be a problem with the actual image that you are trying to crop. There could also be an issue with the dll's you are using.
