OOPPSS!!
Sorry about that. I'm so used to flightsim uploads for FS9 (FS2004) that I forgot that JSGME requires you to have ALL the file structure for it to work.
It's fixed now, so you should have the Data\... structure in there. Just drop the "Bupers_Mod_Beta_2" folder in the "MODS" folder and activate.
I based everything on FotRSU as the base, so you should have no problems.
Future updates forthcoming based on feedback!
