FreeMill will only do a single pass, but you can do multiple setups for roughing and finishing. Or buy something like MeshCAM or Cut3D.

Thanls again Ger, the other issue that I have... and I know you're all going to throw your hands up and laugh... is my machine is 5 axis... and need the software CAM package to support that.

It's very close to having 5 axis CAM package affordable to everyone, they are starting to trickle out there... I'm still searching and trying to find the best one. So far this Madcam looks promising.

Any suggestions there is much appreciated!

Jonny you just crossed over to the twilite zone(;-) You have little choice but to bite the bullet and pony up the cash if you want a 5axis CAM (;-). AND then HOPE it supports your type of 4/5th axis configuation.
