For anyone still following this thread, all has been sorted and the solution to my problem has been fixed. Big thanks to James and Milada from Alliance Gear who spent some time with me yesterday to get me going (2 of the nicest people you'll ever meet by the way!!!)
The line lengths checked out OK but then we simply switched from a 2-1 setup to a 1-1 setup and what a difference. I messed up the first couple of runs out cause it was like flying a completely different kite from before. The bar pressure was significantly less (held on with one hand to clean my nose for the first time ever!

), the kite turned faster and it was more powered up than ever before - we actually moved the lines down a few knots to compensate for the extra power.
So the moral to the story for all you newbies like me still out there....
1) get on these forums. There are awesome people out there with masses of experience and knowledge to share.
2) don't be afraid to have that extra lesson or session with your instructor. Just when you think you are getting the hang of things it's probably a good time to have a freshen up so you can start learning more of the intermediate type stuff like tuning the kite and little changes to help when you're on the water.
3) get out and enjoy!!!!!
