You are an experienced programmer and have a problem with the engine, shaders, or advanced effects? Here you'll get answers. No questions about C++ programming or topics which are answered in the tutorials!
Which video driver are you using? I've potentially found a solution but haven't tested it. Put the water shader at the end and then, inside the water shader replace all "ScreenMapSampler" with "ColorMapSampler". That should allow you to use them together.
