I think it's probably very confronting for her to take on clipless pedals and cyclocross riding all at once. You may need to back off a little and let her get confident with one or the other first.
I went to clipless pedals on the roadie more years ago than I would like to count after doing some silly things in toeclips that had fibreglass straps and wouldn't release me. A couple of good gumby stacks there! I then rode my clipless pedals on the road for years and would never ride with anything else.
Fast-forwarding to late last year, my DH got the mountain bike bug and I decided to join him. The bike I bought came with clipless pedals and I was faced with a dilemma. The concept of riding on loose surfaces scared me spitless (probably a bit like your GF changing to cyclocross) and I didn't want to have clipless pedals in case I couldn't get out in time when I came to a grinding halt on an obstacle I couldn't manage etc. But I also already knew the joy of clipless and felt really insecure without my feet clipped in.
In the end I left the clipless pedals on the bike and used the little plastic platform insert they give you to try the bike in the shop for a couple of rides until I got more comfy. Then I bit the bullet, clipped in and fell off enough times to remove the bark from both elbows and both knees! I'd never go back to platforms now.
I have since been responsible for corrupting many of my friends to clipless off-road and none of them would go back either. I think the main thing here is to be patient. If you want her to ride cyclocross you need to let her do it on her terms - perhaps that means sans clipless for a while. Then clipless can be the big improvement for her when she gets more confident with the whole not-so-smooth surface thing? Either that, or get her riding clipless on the smooth smooth road first?

She can have fun doing cross no matter what pedals she's running. Yeah, she may not win, but cyclocross is more about the awesome than about the medals anyway
