Crash trying to create custom lists after importing some roms.

LB v9.7 on Windows 7

I have seen this error a dozen of times. I think the method to get to it is this one:

Choose a system with roms in your Launchbox Import some roms to that system that you haven't add before. Right after importing, right click on that system and select "auto-generate lists" or something like that (I have launchbox in spanish, sorry about that)

That's it. Maybe is not 100% fail, but it occurs to me doing those steps. Is not a big problem since you can restart LB and create lists again with no issues.

Error:

Referencia a objeto no establecida como instancia de un objeto.
