Compiling error Wont start

Any help ? I cant test the game because of this

Assets/BIG_Environment_Pack/Standard Assets/Editor/Water (Pro Only)/Water4/WaterBaseEditor.cs(8,13): error CS0246: The type or namespace name `WaterBase’ could not be found. Are you missing a using directive or an assembly reference?

Hi @xThomasTv
I’ve got the same problem.
Did you find a solution ?
Thanks
