ContentNodeGenerator.exe error - Torque X Builder 2D

Hi. I'm getting the ContentNodeGenerator.exe error when trying to save my project in Torque X Builder 2D. I checked the forums and it seemed like a common error but none of the work arounds are working. I have tried changing the name of the .txproj file and also importing the image manually into my C# project but nothing seems to help.

Has anyone found another work around for this?

Thanks.
