"The Rom file you've specified does not exist" error in BigBox/Launchbox

[Bernard Bernoulli]

So I just updated Launchbox about an hour ago fwiw. I am not sure if that prompted the error, from what I gather by doing a google search other people started having this error pop up just by adding roms after the initial setup.

Anyways, after I installed the update, I noticed I was getting this error in BigBox and Launchbox with all my NES roms.

"The Rom file you've specified does not exist"

 

I checked the folder in the edit options for the system, it is pointing to the correct path. And that folder has all the roms files.

I checked for duplicate NES XML files in the Data>Platforms folder (as was the issue with another person who had this issue) but only one NES XML file was present.

 

Does anyone know what causes this? 

Can anyone suggest a fix? 

I don't want to have to delete the system and re-add it if this happens each time I remove or add a rom. That would get annoying.

@Bernard Bernoulli When you edit the games, are the ROM paths correct?

I figured it out after checking the folder.

I copied half of my games into the Launchbox folder but the other half were running from an external HD.... which wasn't plugged in.

After plugging the hard drive in everything works fine. 

Thank you for the suggestion.
