error code -39 was returned by the audio driver

Type -39 error (Logical End-of-file reached during read operation)

The Macintosh was expecting a marker to show it where the end of the file is on the disk. That marker is either missing or is in the wrong place. A crash is the most common cause, however a disk error or corrupt file can also cause this.

Solutions: Recovering the file frequently fixes the problem. If it does not, make a clone of a backup, open the clone and try to import from the file that is giving the -39 error message.
In other applications, using an Import or Insert command from inside a new document frequently works around the problem. You also might move/copy the file to another volume.

If you get error -39s in combination with Apple loops, try this:-

"Apparently there is a problem with any Apple Loop samples less than 100MB in size that are set to "loop mode" - you have to go thru w/ the Apple Loop Utility and set them all to one shot mode. Takes a bit of time, but solves the problem."

were you doing sample edits on the file before it gave you this error? i've been having a similar problem

I can't open my DP 5 (Digital Performer 5) MIDI file; it says error -39. This is the 2nd time in 3 days.

What did I do wrong? How can I open it?

More info:

MacBook Pro, 2.5 GHz Intel Core Duo, 4GB of RAM.
OS 10.5.3.

I had opened four Kontakt 3's (one for strings, one for brass....), a Stylus, an Absynth, and a Massive, and two reverb plug-ins, and two EQ plug-ons as well.

I had two chunks open, each with around 40 bars, and around 10 stereo tracks open.

I really think the MacPro can handle all this because my Mac Duo can (although that one is a desktop).

Help!
