Why am I unable to preview the video from my DALSA

Why am I unable to preview the video from my DALSA Genie ethernet camera using MATLAB 7.4 (R2007a)?

I am trying to create a videoinput object for my DALSA Genie camera. When I execute the IMAQHWINFO command as follows:

imaqhwinfo('winvideo')

I recieve the following output:

 Adaptor Name: winvideo

 Adaptor DLL: \\ENG3\matlab-r2007a\toolbox\imaq\imaqadaptors\win32\mwwinvideoimaq.dll

 IMAQHWINFO: 

        AdaptorDllName: [1x71 char]

        AdaptorDllVersion: '2.1 (R2007a)'

        AdaptorName: 'winvideo'

        DeviceIDs: {[1]}

        DeviceInfo: [1x1 struct]

Thereafter, I open the configuration pane for the camera using the AMCap application. Once the configuration pane has been closed, I use the the following commands in MATLAB to create a VIDEOINPUT object:

obj = videoinput('winvideo');

preview(obj)

However, all I receive is a black preview window with the following error message in the top left corner of the preview window:

 "No Sapera Acquisition Device Detected! (Currently Simulating Grab)"

I have been able to preview the camera output using the Image Acquisition Toolbox 1.7 (R14SP1), however, I get the above error message using the Image Acquisition Toolbox 2.1 (R2007a).
