NVIDIA Texture Tools for CS6 Plugin Not Working

I’ve just installed the 64bit “NVIDIA Texture Tools for Adobe Photoshop” plugin into CS6.

I’m now trying to open some .dds files but I get the following message:

“Could not complete your request because it is not the right kind of document”

Everything was installed here “C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)”

Any ideas?

Me too is that problem!
