Skinsoft Messagebox disable

Question

Hi there, 
i am new on this forum. 
I create simple application in c# visual studio for presentation with several components. I wanted change them look, and i download free evalute 20 days version from  http://www.skin-soft.co.uk/.  Concretely Aqua skin, but when i started my application, first run message box with call "...unregistred version...". Problem is here 

private void InitializeComponent(){
 ((System.ComponentModel.ISupportInitialize)(this.aquaSkin1)).EndInit(); // this call some dll method and also create message box
}
Has anyone experienced this problem, such as a message box to disable it or autoclose messagebox when is displayed...

thx for advance
