I'm a student with a deadline, so any quick response will be greatly appreciated.

I want to simulate waves on a beach. I was working on it at school, everything was working ok, but it needed tweaking. I open my save file at home, I no longer see my simulation. I am using the same Cache I was at school, I haven't play in the render settings or anything (using Karma).
I remember having to activate the Karma CPU in the Scene View to see my simulation, but I don't seem to have that option anymore. What is going on?

(I also have no faith that my teacher will answer, so you guys are my last hope, pretty much.)
