XGen not working anymore.
 

Hi everyone,

I've only just started learning XGen so I don't really know what I'm doing with it. I was happily working, starting to get some decent results.

When I suddenly pressed something by accident, I think it was ctrl+ some key around the S button. Now I can't preview the hair, It's not showing up in renders, and when trying to open the scene in a new window of Maya all my guides are gone!

I haven't closed the Maya window I was originally working in so I still have this:http://i.imgur.com/y9r7zsQ.jpg

Does anyone know how I can recover my work? It took me most the day to get to this stage and I really don't want to start again.
