In my students' final exam in a course using Excel I presented them with an assignment that included the creation of a macro-enabled workbook. The students were to upload this workbook plus other files into our course management system (Blackboard). I suspect that the CMS attempted to further compress the student submissions. As I attempt to download these files for grading I'm presented with an error dialog box with the title "Copy File" and the error code 0x80004005: Unspecified error. The error has repeated on all student files.

Needless to say I am quite anxious to find a way to retrieve the file. It constitutes a large percentage of the grade for the course. I am open to virtually any suggestion.

Many thanks.
