NVIDIA Texture Tools plugin

I recently applied NVIDIA Texture Tools (http://developer.nvidia.com/nvidia-texture-tools-adobe-photoshop) which allows the exportation of .DDS files.  My problem arises when I try to actually save my project as a DDS its say "..because of an error".  Also sometimes I try to import a DDS and I get an error that says "...problem with file-format module interface."

Anyone familiar with this plugin that might be able to help?
