With rescpet to "Failed to read xxx samples"

I sent you an email directly.

Dear Support people,
As indicated in the list of topics, I seem to have that problem too with version 3.0.2 that I bought last week to convert (obviously) FCPX XML to AAF.
Using OSX 10.10.1
FCPX 10.1.4
X2Pro version 3.0.2

The generated error message is:
An error occurred converting Final Cut XML to AAF

Writing AAF file
Adding assets to AAF file
Adding essence for asset [0404S73T24] to AAF file
Adding essence data to AAF file for portion 0 of asset [0404S73T24]
Reading audio data from audio extractor : 174762 samples
Failed to read 174762 samples


No AAF file has been generated.
X2Pro Audio Convert 3.0.2

Trim handles of 1, 2 or 4 seconds don't seem to change the error and also it seems that selecting/deselecting "trim embedded audio" is not changing the behaviour of the error .
Attached is the FCPX XML file that I wish to convert ( possibly rather soon...)

Would there be a possibility to obtain version 2.5.1 as I undersand form the forum that that version is likely to work correctly ?

Many thanks in advance and kind regards
Jan
