UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
This is a series of screen shots of the results I get when I try to use the tool to remove vignetting. I get basically the same result regardless of the integration.  Any ideas of where things are going wrong would be appreciated.
Thanks
Chris

I had already reviewed that tutorial and believe I am following the guidelines. This is an RBG image from a Sony CMOS. I have darks but no flats. Light pollution tool and star calibration tool work fine. I have tried all three of the models, and while the two KangWeiss are a bit better, I am still left with an unusable image, regardless of stretch. Is is important to stretch it out to the extreme before using the tool? Am I oversampling with that many green boxes?  I also watched the video tutorial and can't see anything that I am doing differently
Thanks.... Not the end of the world, but it would be nice to have it work

The vignetting tool is not so effective. Much better to go directly to the light pollution removal tool, which is takes care of gradients and vignetting and background neutralization in one go.
