Can't fit design in Cyclone V GX

Hi everyone,

I'm trying to complete the My First FPGA tutorial (https://www.altera.com/content/dam/a...first_fpga.pdf) and everything works perfectly up until compilation, at which point it gives me error 11802 ("Can't fit design in device"). This is confusing as the flow summary doesn't say that a significant amount of anything is getting used.

I saw that this was an error with Quartus II but I'm using Quartus Prime Lite so I can't find anything else on it.

Any help would be greatly appreciated :)
