CRT is pretty much a do it yourself thing at this pointy. All indications is that Doug has passed on some time ago sadly, and anyone that still has CRT pretty much needs to tweak it themselves.
The manuals are all available on my website below if you don`t have them. There is a learning curve, but it`s not hard to do if you follow the manual step by step.
ALso., you might post on my website forum at the top of my web page. There`s a lot more CRTers there than there are here..
