Some files saved in Digital Performer 2.5 may return this error. The error is a result of a file saving problem that has since been corrected in a version 2.51 update. The update is available on our downloads page. The update DP 2.51 will not only open corrupted files that return this error, the update will also resave corrupted files without the Error=103 corruption.

Go to MOTU's Downloads page (link below), click onto the Digital Performer link, then click onto the link to the DP 2.51 updater.
