Importing Blender Water to Unity

Hi everyone! I am currently working on a game in Unity Indie and using Blender for various modelling aspects. In order to include more advanced water in my game, I created a plane in blender and added water ripples through the use of an animated normal map, a method I learned in this video for the Yo Frankie Project. There seem to be no issues when I try to import my water into Unity (the plane, material, texture, normal map, and animation are all there) but the animation never plays. All I can see is the plane with its texture and a still image of the normal map. Is there a reason I would not be able to import this animation into Unity Indie, or is it possible I just made an error somewhere in the importing process? Any help is much appreciated!
