Ok, lots of people seem to be having trouble with the second message.
Big big hint wrote:Look at the shape the letters make. W is water, X is barrels/bridges, O is floor tiles, blinking O's are the path to follow. There is an arrow point right which is the way OFF. Look at the I and the V top left. What else could they be besides letters? An arrow pointing down? The way ON perhaps? Now place that floor plan on top of the floor so that the diagonal O's go over the coins.
If you still can't get it from that there's no hope for you all.
You must have done it wrong then. Follow the directions from the tile directly below the sign and don't deviate at all. You should end up at the water's edge about 2 tiles up from the bottom. You won't see a bridge at first.
