LaunchBox previously worked fully. I imported a bunch of PSP ISO files, and everything downloaded successfully as far as I could tell.
Then, to be sure, I tried to "Update Medata and Media for All Games". The metadata downloaded successfully, then at the next stage, which I suppose is media downloading, at the very end after it downloaded the last file (e.g. 2400/2400 downloaded), I get a message saying that "LaunchBox encountered an unexpected error."
There was an info box below with the following text (a screenshot is also attached):

Can anyone help with this? What happened and what does this error mean?
Thanks.
