No one sneared at you.

I pointed you to the downloading faq. It is loading just fine for me. It explains which version of Knoppix is which, how to tell the native English version from the German version, how to tell the DVD from the CD, how to get the German version to boot into English and more, including that the best and fastest way is not to use any of the mirrors at all. You might even be able to "fix" your German version if you follow the instructions without needing to download everything again.

I have no idea why you are crashing, and you don't give any info that would help me figure out why you are crashing.
