Vegas Pro 19 keeps asking for authentication every time I load it up. It has my serial already autofilled in and I just have to click YES and it goes through the authentication process, but this happens every single time I load the program and is annoying and frustrating. I have reinstalled it over and over and it doesn't fix the issue and I can't find a fix anywhere online, nor does Magix offer any help that's even close to relevant. Does anyone have any ideas?
