Okay, I used to play Minecraft 1.8.1 back in the good ol' days, and after a couple years, I felt like giving it a try, I stopped liking it because they kept adding things not necessary, like Iron Golems, but anyways, when I open Minecraft it is just a blank screen, I can see through it to my desktop and I can hear the regular Minecraft music in the background, through my speakers, I just want to play Minecraft, if you guys have any suggestions, please tell me, I haven't done anything yet, and am looking for an answer. Thank you.
Added (1). I have not installed new mods; I got a new computer in the past two years, so nothing new, .minecraft is there, but I don't find any reason to uninstall it if I just installed it.
