Hi, I had a problem with Windows 10's performance.  It was very stutter and unresponsive.  So I had to go back to windows 8.1 Pro via CD/DVD that came with my laptop.  After installing Windows 8.1 successfully, I wanted to refresh my computer from the advanced start up option but the refresh for some reason couldn't do what it had to do.  Since I couldn't refresh I lost the cyberlink media suite and the latest version of Stagelight.  Cyberlink I wasn't worried about because I could just download it from the dell download center, what I am worried about is Stagelight.  I don't see a way to get that one back.  Would someone kindly help me out to get Stagelight back please?  I use it for the New Music ensemble at my university as an electronic accompanist.  It's very important to me.  Thanks in advanced.
