Chances are, you have a floor that should not be waxed, and the product that you are using has become built up on your floor. The wax needs to be removed, and then you will have to find a suitable product that will not cause this problem in the future. You really should find out what type of finish you have, but I would bet it is polyurethane as this is most common these days.
To remove the wax there are products that you can buy at a local hardware store. Also, check out this post for more ideas for removing wax build up.
www.findanyfloor.com/forum/Repair/... I like Armstrong's hardwood cleaning products. They are safe for your hardwood floors and will not cause build up. As long as you get all of the wax off, you should be able to make your floors shine again. Hope that helps you!
