Error Code with No Apparent Error Number

[AndrewW]

Anyone knows what this means?
OK, I know what it means in programming terminology,
but what does it means when Replay Music Throws this error?

It doesn't appear to have stopped anything working.

Did you change the location of your output folder? If so, as an example it was a USB and it was not there, that could cause this issue.
