The kite doesn't get off the ground, let alone in the window. Is there something I'm doing wrong?

Check the break lines. If it is too short, the kite won't get off the ground.

you got the lines the right way round, i mean ya not got brakes mixed up with main lines or is the bridel lines twisted and knotted??? should of come with a booklet with a gide in the back PROBLEM section

Take all four lines off the kite and lay them out and make sure that they are even. If they are not even you need to even them up and the kite should take off. If the brake lines are too long which thats what it sounds like the kite will just sit there and not take off. Hope this helps.

Correction if the brake lines are too short then the kite will not take off.
