I have recently purchased a Nikon D50, and a Loreo 3D lens attachment. I am have been teaching myself how to use this camera over the past few months, as I am relatively new to photography. However, I have one problem I cannot figure out how to fix- I am unable to get the camera to take a picture with the flash when this 3D lens is attached. Does anyone have any idea why this is and how I can fix it? I have played around with the white balance, ISO, etc.. in order to get decent pictures in low-light situations, but would really like to be able to use the flash as well.

Thanks in advance!
