Looks pretty good that - would soften the lip colour slightly, so it is more skin coloured. With regards to the PS problem, it could be something to do with memory, usually it would say 'not enough memory to complete the action' or something like that. But occasionally it will give the message you describe.
Thanks Kit, i'll try and change the lip colour now.
Btw, when you mean memory, do you mean RAM?
Edit: I've changed the lip colour
