Develop module does not start in Lightroom 6.13
I have finally managed to install Lightroom 6.13 (Windows). I can see my pictures in the "Library" and I can move one picture to "Developer" by the D-key. But when I want to ajust something, like contrast, the "Developer" says "doesn´t answer", see picture below. What shall I do? What is missing? I have unstalled Lightroom two times now but with the same result. I have bought Lightroom.
Can I replace the Develop.lrmodule?
