Confuse about the word "requires"

[rapips]

*Sketchup version 7.1
I already installed sketchyphysics 3X(latest version), when I try to play the simulation, I notice that in the upper Left corner of my Workspace, there was a message like this "Requires SketchyPhysics3 RC1", yes it is color green, It always pop up, every time I start the simulation.
How will I remove this?

I dont know how you can get rid of it, but its purpose is to show anyone who opens the model that it runs in sketchy physics 3, so its not doing any harm.

Like remus said you have nothing to worry about as you have sp3X. If you want to hide it go into layers and deselect the water mark text.

You can also change the text to be a single space. Double click the text, press space and then enter twice.
