If the object is coming in grey, then it's not been UVMapped, so that material file is probably an *.mtl file.  Which means that there are surfaces that you can add Procedural materials to, but no UV co-ordinates.

Okay, so hover your mouse over the object, and right click, here you can see that I get a list of the items positioned under where I had the cursor hovering, and amongst these are RedWine_1 and  Glass_1
