The German language plug-in.

The French language plug-in.

Sounds like the archives got corrupted during the download.

Make sure, when you first download the files, that you are downloading them as binary files. Most browsers should just do this automatically, but occasionally one might prompt you to save the file formatted as "text" instead of "binary" or "source".

You could also try downloading them using:
wget http://moodle.com/download/moodle-1.0.2.tgz

On most Unix machines, you can unpack the .tgz file using:
tar xvzf moodle-1.0.2.tgz

and the zip file using:
unzip moodle-1.0.2.zip

Why do you want to? Personally, I'd rather you didn't!

I don't have advertising resources like commercial companies. Like most Open Source projects, I rely on links to my site to help spread the word about it. The "made with moodle" icon is fairly unobtrusive compared to a banner or something.

Is that too much to ask in return for something you got for free?

That probably means you haven't defined an admin user yet - Moodle is asking you to set up an admin user.
