Media Manager Error Code 134

Hey, everyone!

I'm trying to use Media Manager (FCS 1, FCP 5) to copy all the necessary files of a project into a folder and archive it so I can wipe the disk the project is on and re-purpose it.

Int the middle of the process, I've gotten an error code of 134 (not 34!) and the option to skip the clip, retry or abort. What does this error mean? What has gone wrong and needs to be fixed so that I can complete the process?

Thanks!
