change color scheme layout

hi there, suddenly my unity editor its in grey color like unity 2.6, and i like to work with the dark scheme in unity 3.0, but i cant change that, and restore factory setting doesnt work, any help please?

Do you have Pro?

no i have the 30 days trial

I guess your trial ran out then. You need to buy Pro if you want the dark scheme.
