Cry Engine

I tried to do cryengine at uni and it worked then when I came back from my doctors appt. it wouldn't work and no-one could get it working. I've tried to download it but there isn't a mac version (that I can find) and I don't know anyone who would let me use their mac computer for an extensive amount of time. Plus Im not in wellington anymore (home for the break) so I can't use the uni ones.
