Dear Roland,,
As I said before - We do not recommended make upgrade of our Joomla Virtuemart Templates, because they have some custom HTML, and it can influence for it work. For example , destroy design.
Please, use default settings and do not make update of Joomla and Virtuemart.
Now, need check - what is the reason, maybe in your action, maybe in our template. So, for good work of template we do not recommended make upgrades .

2) As VirtueMart is a Joomla component you should also install the Joomla language pack. You can check the detailed tutorial on how to install Joomla language pack. As soon as the Joomla language pack is installed you can proceed with the VirtueMart language installation.
