Cubase 12 download manager error

Help me pls. Dl manager is stopping when only 1 MB DL left. It is not responding. I started it once before but the icon doesn’t open it and it sad it can be replaced. So I click on the dl manager exe and reinstalled it.
I did all the things as it said in download manager guide again. I first downloaded cubase 12 (application required). I don’t know why but there is an icon on desktop and I could open cubase. However the download manager seems not responding again after only one MB left. the bar is blue. What is the problem? :frowning:
