I purchased online from the MAGIX store. Installed, entered product keys, and registered successfully. When dbl clicking either application (MS17P or SF), the splash logo appears, you can see that the applications will begin to load and then the splash logo closes and nothing happens. Nothing loads. I had Movie Studio 4 installed and it loaded with no problem. Now, I cannot get Movie Studio 4 to load. I have uninstalled and reinstalled and nothing. I don't know what to do. I'm running WIN10 and haven't had any issues until this. Any suggestions?
