Cannot add roms

[Kemlo]

Hello all, hopefully you can help, got my rom set to 50gb (to fit on a 64gb card), scrapped everything on my pc, and now whenever I try and add the games to retrostone it keeps giving me this error message -

emulationstation: /home/pi/emulation station/es-app/SRC/filedata.cpp:217: void filedata::addchild(filedata*): assertion 'mtype == folder' failed

I have transferred via FTP, samba and directly to the SD card via Linux, do I need to transfer less at once? Help!
(This message occurs after I add the ROMs)

If you're comfortable with command line, quit ES then run it with:
emulationstation --debug

Command line isn't an issue, deleted the gamelist XML and media folders, everything running ok now (far as I can see) scummvm will just have to slum it lol.

Still suffering the slow down however ( )
