on the subject of valhalla... did you know that you can use a text editor to read the main executable (yeah you probably did), but the interesting thing is near the beginning of the garbage of text is a bit about the manual protection...
it displays all of the 7 or so key words you need for the protection... try and error will give the right answers to the questions
infact if you get a hex editor, you can rename all of the words... i did (am i 1773 cracker or what
), i renamed them all to... <blank>, and i put a bit of text in there to say just press RETURN!
i was very suprised to find it still worked
