Root Element Missing Error when importing MAME Roms

[jmy102]

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?

What version is the Mame executable you are using?

I believe this is the error spit out if someone tries to use the full mame import against an older version of the Mame executable or when using an "unofficial" Mame emulator.

When I try to to do the import I choose this option... which automatically downloads an installs 0.257... the same as my ROMset

So.... I completely formatted my SSD, did a fresh install of Windows 10, and reinstalled LB. And it WORKED this time. Still have no idea why, but at least it worked. Thanks.
