[Unable to import some rom files]

I’ll try full import.  Didn’t really want all the games imported - but I’ll see if that will work.  
 

still it should allow an import.  Before I try full import, I’ll try with suggestions provided. 

[Unable to import some rom files]

I am new to Launchbox and just trying to out, but had planned to purchase if it worked well. I only play a few games, and I have a problem loading Pac-Man.  
 

launchbox v12.14

MAME v245 with merged roms 

I can run pacman just fine. I can search/find Pac-Man and it plays “normal”.  I can also run puckman in MAME, so I know the emulator/roms are good.  

I tried to import Puckman, and it failed.   I didn’t capture the error, but when I try to re-import, it doesn’t give an error - but it doesn’t import it either.  I was able to import my other mame roms just fine.   
 

Anyy suggestions?   If it makes a difference, I was (edit) not importing the roms “in place”; I was copying or moving the roms.  I put the mame folder directly under Launchbox folder.
