I'm trying to watch a video and it gives me the message, "Sorry, you may not access this content." I'm pretty sure I've figured out the problem, somehow my birthyear got set to 1995. I, however, am 19. It won't let me change my birthyear, can someone with administrative power please help me with this?

Not all of us do. Atheists of European descent or culture do, but that's really irrelevant to us. Also, because the calendar(s) of western civilization were made up decades and centuries after the death of Jesus, the truth is Christians don't count the years with any real accuracy either if they are basing it off of a specific point in his life. Also, Jesus was born in the Spring (according to the Bible), not on Christmas; you folks don't even have that right.
