Hi there, I just downloaded the premium version of this template (002041). Joomla 3 was already installed and I already installed the as template too.
But the extansions file I am not able to install, because joomla always brings this error:
JInstaller: :Install: Die XML-Installationsdatei konnte nicht gefunden werden.

in English:

The XML Istallation File could not be found.

What can I do about that?

The css is not shown correctly and I thaugt, that it is because of this missing file. (For example in the install joomla the main navigation's class is "nav menu" in the template it is as-menu)
I don't know how to change that. I thaught the extensions file will help.
