Nobody is blaming anyone.
Since this one was solved long ago by somebody who shouldn't be guessing at Rookie Puzzles (i.e., me), I removed the offender's reply, took away the awarded point and tagged the puzzle so active Rookies would see it. I PM'd you at the time, but it seems you forgot.
All activity on this puzzle on or after April 24, 2009 was the result of the correction cited.
