ArcMap invalid rastor dataset

Question asked by lizzieapala on Jul 10, 2014

I am new to ArcGIS and am trying to use ArcMap. I have been told what file I am suppose to download onto ArcMap but its not working. My goal is to take this data file and project a map from it to match another dataset map. It keeps telling me that its an invalid rastor dataset and it failed to create a rastor layer. What does this message mean? what is rastor data?
