How to make my movie play again on my laptop (Lenovo G50)?

I have played 3 movies before on it no problem, right now I tried playing my movie again and I had an alert saying to update my movie app for better or faster experience, I tried to do so but in the end it said it was an error on my laptop so i just cancelled it. I deleted absolutely everything related to cyberlink power DVD and every time I click on my lenovo power DVD12 app to play my movie, the same alert shows up "CyberLink Power DVD" is currently running, you must first close it before proceeding." I uninstalled the cyberlink program, deleted files etc. So i have no idea what else to do. I even restarted my laptop 5x to see if that would work. Does someone have any idea what I should do or could do to play my movies again?
