I really wanted to argue and say "No I didn't I've been using this mod for years I know I downloaded the right one" but apparently I DID download the wrong damned modpack and am dumb as a sack of hammers.
Thanks for the help!
Went to install the latest modpack and got the first message, installed it thinking it would create the file like always, installed, went to launch, and this happened and game will not load.
