Hi
Seems there are issues with the language packages: http://virtuemart.net/community/translations/virtuemart
I installed vm 3.0.6, then I downloaded my language pack, installed it and wasnt updated, had to manually download the file from transifex, rename it and upload it via FTP. So 2 issues:
1 - Seems the packages are not being updated in the URL mentioned.
2 - There are duplicates of several language packs in that same URL.
I just noticed a 3rd issue with accents in tooltips which aren't displayed correctly:
