Hints

officialQuestion: Four words within Einstein. Format: "word1 word2 word3 word4.fnw". The last three digits from the broken link in block 9 are set as fnw for this block. German words allowed.

Published answer
Solution was "Moonwalking with ein Stein.fnw". Explanation: Four words within is two words with and two words in. The two words with are those from the famous book titile that shows up in a Google search, the two words in are just "ein Stein" (a stone in German). Final Update and apology: As several people noted, my mistake in hashing block 9 happened in this block too. Again a line break at the end from copypasting from a draft in a wordprocessor.
