the arduino displays an error I cannot comprehend when I try and program it for the crystal display. Can someone explain why it acts like this, even though the LED board has turned on, and would work if not for the error.

The arduino IDE (and every other development environment) is very strict on how you type things I.e. Uppercase and lowercase.
Basically there error message says it can't find the file because it is looking for a .h file named liquid crystal with lowercase. Try this:
#include <LiquidCrystal.h>
Have a nice day!
