This was working fine for us @ 9.3.1; however, upon upgrading to AGS 10 it will not print if we use our aerials layer. I am getting a 500 internal server error when the aerials are printed. All other layers (basemap, etc) print fine.Here is the error output (via Firebug):
[NullReferenceException]: Object reference not set to an instance of an object.

Any ideas?
