I am running SC 2007 R11 SP2. The Depth type options are greyed out and I cannot select the "spiral" option. I cannot find a setting that triggers this, or any other thing that turns it on. It's very frustrating. Even more so, that my version at home has this option, and works like a charm. We have let out service agreement laps so I cannot call Solidcam to ask. Any help would be great.

I'm having trouble casting my mind back to that version.
I assume that you are trying to do a 3D Milling Semi Finish op in which case I think you control the depth only in relationship to a surface offset as Spiral machining is a 2D toolpath draped/projected over your part.
Another reason why you could have certain options greyed out is that as SolidCam sell you a modular package you may not have bought certain options at the time in which case they'd be just Grey or they may have had a time limit on the licence if you got the options for a trial period.

I strikes me that the easiest way around your problem would be to program your part at home !!!
