Try this instead. Get some graph paper and cut out rectangles to scale to represent each room you want. If you use the standard 1/4 inch graph paper, it usually works well to let each square represent a 2 ft or 3 ft square. Label each rectangle with which room it is.

Then sit down at your kitchen table and push the pieces around until you have a layout that you like. You'll probably find that you have to make some rooms larger or smaller than you originally planned. You'll see this when you're forced to overlap two pieces or leave gaps between some pieces.

Once you have a layout you like, tape the pieces down then get a fresh sheet of graph paper and DRAW what you have. (You can tape two or more pieces of graph paper together - matching up the lines carefully - if a single sheet isn't large enough.) Use a black felt-tip pen to go over the lines then scan the image or, lay it down flat and take a photograph and post that. Or, you can go back to floorplanner.com and DRAW what you have created.
