This happens when you metadata.xml file gets corrupted. There are two work arounds:

Run the installer over the directory again so it puts a good file in there (this will NOT remove your library data).

or

In LaunchBox go to Tools > Download and there is an option that reads similar to "Force Games Database Update". Press that and it'll download a new metadata file.
