German not working

[peter@.....com]

hi, I just aded the German language to my webshop, next to Dutch and English. Everything works fine except for the German checkout wit OPC. Both wit logged and unlogged, after clicking the 'confirm' button, I get a message that name, adress etc. are not filled in. I am probably forgetting a very simple setting, but cannot figure out what it is. Can you help out? Thanks!

Config: Joomla 2.5.22, VM 2.6.6 and Onepage 2.0.247.060614

hello peter, i just sent you an email. i've see those messages on the standard vm checkout, but opc should be able to filter them. i would need to see your site to know what the problem could be.

in general the language should play no role on the checkout functionality.
