Nostalrius Begins - Quality wow vanilla realm (1.12)

When I start the game up, it auto-minimizes. I have tried multiple times to get it to work. I can click on it in the taskbar and it will go full screen for a few seconds, I will hear the video playing, then it will just reminimize. I remember this happening a long time ago to a different game, but I cannot remember the game nor how I fixed it. Any help out there? Thanks in advance!
