Well first of all id like to thank chris and mike for opening the rooms two days after i should have gone home for christmas for me as these two days made a whole lot of difference in my rooftops project.
I have spent the past two weeks fretting over this project as yet again i was having unreal problems (the lighting wasnt building) and until monday this week i had woried that it would never be finished, ansd after weeks of helping me mark just happened to utter the phrase "have you moved computors" at which point i discovered that it was not my fault but the computor i had been on.
This has taught me a valuable lesson dont trust the computors at uni, and before you start deleting things move.
