I am working on a vacuum kiln model that I imported from Solidworks using the ProE file extension (I used it because it imported my assembly in one shot). There are three materials so I made three separate domains, one for each material. I am using the module "Heat Transfer with surface-to-surface radiation (ht)".

The sub-modules under Heat Transfer (ht) I have selected (and modified) are:

Heat Transfer in Solids 1 (Opaque)
Heat Transfer in Solids 2 (Opaque)
Heat Transfer in Solids 3 (Opaque)
Thermal Insulation 1 (All surfaces without radiation)
Initial Values (Room temp with Radiosity = 0)
Temperature (I set the heating bands, on one face) to 1500K - estimated from experiment)
Surface-to-Surface Radiation 1
Surface-to-Surface Radiation 2
Surface-to-Surface Radiation 3

I am getting a consistent error that says
"Unknown property. - Property: window".

After I click OK the error message becomes
"The following feature has encountered a problem:
-Feature: Study Step 1 (sol1/st1)
-Error: Invalid property value.

When I trace the error back the following error description pops up:
"Invalid property value.
-Property: title
'Title' is a string

I have not typed 'Title' in for any property values and I tried setting all property values to "user defined" then inputing a constant. I also removed the materials that I was using from the Materials Browser (tungsten, molybdenum and graphite). Any ideas or experience would be greatly appreciated.
