Have just upgraded/bought Snagit 2019. Have a software key and link to download. Every time I try to use the link nothing happens. I keep getting a 404 error page. In fact, I'm getting a 404 error for ANY link that has anything to do with downloading product. I just now opened a ticket. Tried multiple times with Edge, Firefox and Chrome. Not sure what to try next. Yes, I've also rebooted PC, cleared cache and cookies, etc. What should I do? Please Help!!!
