Let me preface by mentioning that ArcGIS administrator and licensing is fairly baffling to me.

I am using ArcGIS 10.0 and am attempting to use the Spatial Analyst tool in ArcMap. When I go to Customize --> Extensions it says: 'Spatial Analyst (License not available).

How do I find out if the the extension is or is not licensed?

If it is, how do I find out if I am using the "Concurrent Use" product?

If it is not, am I SOL?
