Can not export an AFF from XML file

Thanks. The issue was some archival audio. I removed it an was able to create the file.

The file it is complaining about is "/Volumes/POW_WIVES_BACKUP/POW Wives - Disc 1/title01.m4v".

1. Can you play that file in QuickTime Player?
2. If you remove that clip from your project are you able to convert it?
3. Can you make that file available for us to take a look at?

I have been trying to create an AAF from an XML off of Final Cut X. The video is 4 minutes in length and should not contain any questionable audio files. I keep getting this error message:

Writing AAF file
Adding assets to AAF file
Adding essence for asset [title01] to AAF file
Adding essence data to AAF file for portion 0 of asset [title01]
Reading audio data from audio extractor : 524288 samples
Failed to read 524288 samples
Error Reading audio data from asset [-2209] [The operation couldn’t be completed. (OSStatus error -2209.)]

Suggestion: Please ensure that the movie contains a supported audio format.

No AAF file has been generated.
X2Pro Audio Convert 4.0.17

I am using X2Pro 4.0.17 on an iMac OS X Yosemite 10.10.5

The XML is attached.

Can you help?

Thanks!
