I've made a video no problems. Then, about a month ago, I became unable to add new files. You click 'new file' and normally the window pops open to pick files from your computer. That doesn't happen anymore. Right click to add files, that doesn't work either. I also can't even edit the video project file I already made.
I have uninstalled and reinstalled cleanly, with help from a professional, and it's registered too.
I'm hoping someone else has had this problem and can help me, cause the people at NCH are zero help.
