Hmm, that particular error can only happen if max's built in viewport DIB retrieval (essentially viewport screencap) function fails. It's not even a tyFlow function so it failing on your machine is very strange.
Can you open your maxscript listener and enter the following:
display (gw.getviewportdib())
And tell me if a window showing a viewport screencap pop ups?
If the tyPreview issue happens consistently across all scenes, can you maybe send me a max file from your machine where the issue occurs? Just so I can double check the saved tyPreview settings in your scene to make sure nothing else weird is going on.
