Material Not Applying in Simulation

I am a student using SolidWorks Simulation for the first time and am having trouble.  I have downloaded the software on my computer and everything works properly except one thing.  I can apply a material in the "Modeling" portion of Solidworks and all material properties show up.  Unfortunately, it doesnt not carry over into the "Simulation" portion.  Then, even if i manually go in and try to apply it again, it simply doesn't let me.  The appropriate materials box shows up, and the material properties are all defined, however when I click "Apply" nothing happens.  This occurs for files I have created as well as the SolidWorks Simularion Tutorials which are given.  I can apply forces and fixtures appropriately, however I can not simulate because it will not let me select the material.

The most frustrating thing, is that I can use it on a friends computer and everything works properly.  I follow the same steps on both computers and yet mine will not work.

I have uninstalled and reinstalled the program and still no success.  Any ideas?
