Issue with generic text file having extension .dcw

[ElvisofDallas]

I used xattr to remove the restriction and reloaded ql/finder, but I get this error when debuging (and no content other than the icon and filename when trying quicklook):

Can't get generator at /Library/QuickLook/QLStephen.qlgenerator

Any thoughts on how to resolve this?

Thanks in advance for the great tool!
