Having problems with Gaia Spawners

Unity 5.3.5f1


When I run the 3rd step in Gaia the water comes out pink for some reason Also when I run the object spawner none of the farm buildings appear nor do any of the rock piles although everything else seems to be appearing. Any thoughts on this would be appreciated. I am no expert in this engine and know very little about textures and materials. Thanks.

Pink textures indicate a problem with the shader and texture:link text

I actually believe this had to do with the version of Unity I was running after upgrading to 5.5 I no longer have this problem. Although there are a few objects that it is suppose to spawn that are still missing textures and shaders.
