If you only got her yesterday then it is still very early days. Don't try to rush things and be guided by her - if she seems stressed and scared, then back up a bit and just take things a bit slower.
I adopted a robo last summer and she is still quite skittish. If I'm at her cage, then she comes running to say hello, and she will take treats from my hand but try to touch her and she's off, she's not having any of that!
I think we have reached our limit with her but, although I can't handle her, she still seems to be quite a happy wee thing.
I also adopted a little russian back in Feb and she is the complete polar opposite - she is super friendly, very cheeky and loves coming out for cuddles.
