An error occurred converting Final Cut XML to AAF

Writing AAF file
Adding assets to AAF file
Adding essence for asset [BUMPER OUT + ALPHA] to AAF file
Adding essence data to AAF file for portion 0 of asset [BUMPER OUT + ALPHA]
Reading audio data from audio extractor : 868067 samples
Failed to read 868067 samples


No AAF file has been generated.
X2Pro Audio Convert 3.0.2

FCPX 10.2.2
Mac OS 10.10.5
Trim embedded audio = YES (NO also doesn't work)
Trim handles = 3sec (2sec also doesn't work)

I tried to delete this file and export another XML... I get the same error, but with another file.

Also, for your information, I tried another XML used before the update of X2PRO (same computer setup, same FCPX version) that worked, but now I get the same error with a different file name.

Can you contact me soon for a quick fix for this, because the deadline is really close for us! Or can I download the old version again?

Thank you!
