Hey guys,
I'm hoping someone can help me here. I need to sort this out really soon, and I'm completely stuck!
So basically. I created an animation a few months back (in cs4 at the time I think) - standard 550 x 400 px. All finished, everyone was happy. I've now been asked if I can change the dinensions of the animation to 1366 x 768 px. I'm now running cc. Sooo... I looked it up, did what I was told -
go to spanner in properties
type in new dimensions, then click on scale content
Did all that, but everytime I try to do this, it moves elements slights. E.g everything has randomly dropped 100 px.
So I tried scaling to 712 x 400 (in the hope I could scale up later on) but still had the same problem
I got my info from this: http://tv.adobe.com/watch/cs-55-web-premium-feature-tour-/flash-profes sional-cs55-scaling-assets/
But obviously it is for 5.5. But I did notice that he changes settings in the preferences. Which I dont appear to have in cc.
Can anyone help?!? I'm really stuck on this, and I need to sort it out 
Any help would be wonderful! 
Thanks very much
Jen
