I have a problem with my MAGIX Video deluxe 2014. I installed this software after changing hard disk on my laptop (operating system Windows 7 Home Premium). Now it does not support sound of video files with extension "MTS". When I want to put such file to the timeline, software suggests to upload the set of extensions. I confirm this by pushing the button "download". The process seems to start, but immediately stops without further effect. Please, help me to solve this problem.
