There is a fine line between a difficult puzzle and an illogical one, this falls into the latter.

As there was no indication of which piece of clues fit into which piece of the puzzle, they have to result in an error message to guide you to the answer. Moreover, there is too much guesswork (as they give you many clues without any hint of which is which) and we basically solve some of the puzzles by luck.
