The new language pack is already installed, but i can't change it. In the previous versions was german the default language pack after install. http://www.klaer.com/Language.jpg
I am having the same problem, I installed the language packs just to see if my labels would be correct in those packs, but they don't seem to upload correctly (they are the 7.5 ones). There is an orange exclamation mark to the left of it, and i can't figure out what it means.
But on another Linux Box, i installed the language-pack before i have uploaded the final key. So if no key is installed, you can select the language you prefer to use later, if you dont have additional language-packs in your key.
After inserting the Activation-Key, the language settings would stay at the last selection and all other langages are hidden.
On the machine i had the Problem too, i switched back to the temporary key i have received from SW-Soft, then selected the prefered language and then switched back to the final-key.
