I'm just a little frustrated here. I think I've tried everything that I can find in the forums. And yet, every time I try import MAME 0.257 Fullset in LB I get the same error... "Root Element Is Missing". I've completely uninstalled LB, cleaned my registry, reinstalled LB, wash, rinse, repeat without success. And this is the first thing I try to import. I am able to successfully import any other ROMset without issue. My install is always in C:\LBOX. My Roms and CHD's are in separate folders, also in C:\LBOX. OS = Win 11. What am I missing?
