VM not working in one language - site with multiple domains

[hrga]

Hy! sorry if this was answered but I don't know how to name this problem that I have and how to search for it.

I have site with three languages and tri domains that change depnding on language. VM works in two languages that I dont need and third one Spanis/Mexico does not.

Here are links:
MEX http://www.aprendeavolar.com.mx/mex/arnes/solo.html
EN http://www.paraglidingcroatia.com/en/arnes/solo.html
HR http://www.pjkflumen.org/hr/arnes/solo.html

The thing is for instance if I make link like this
http://www.aprendeavolar.com.mx/en/arnes/solo.html (en instead of mex) it works

I modified SEF for Joomfish to show me mex instead of es so maybe that is the problem but again everything else on website works.

I am realy getting desperate with this. Thx that you read and help

Hi,
Both are too old. Please consider to upgrade your joomla version to 2.5.x, read here: http://forum.virtuemart.net/index.php?topic=106865.0

Your vm version is too old also, no one use it anymore, please consider to upgrade to 2.0.12e
