Acidental delete of blue ray software

So I recently bought an Asus I am very happy with my purchase it came with the blue ray soft ware and it worked but then I was deleting some of the free trial things that came with the computer and accidentally deleted the software that played my blue rays is there somewhere that i can get just the software for free? Or is it still somewhere that I can get it back I deleted it a while ago but I just now tried to watch a blue ray and it no longer recognizes the disk I even tried using the movie I have watched on my computer (blue ray) and it still didn't work
