The Freedom Flight kit is rather complicated this year. I've had several breaks in the ribs myself and misunderstood instructions multiple times. How much are you winding? The plane will not climb if you're winding around 300 winds (20ish turns on a 15:1 winder). Dave's instructions recommends you put the rear post of the wing mount slightly in front of the middle of the laser cut motorstick (where you glued two pieces from the laser cut sheets together to make a motorstick) and have the CG about 1.1 inches in front of the rear wing post. Add some clay towards the front to make the CG more towards the front.
If in the end, if you still cannot get it to fly, and if you have time, I have seen recommendations for using the Vanguard P-18 kit, which is less complicated and takes a lot less time to make. It's only 15 dollars and can be bought here: http://www.lasercutplanes.com/index.php?p=1_2
Posting the measurements of your plane and pictures would probably be helpful for others as well.
