Please explain more clearly. What do you mean by "Get your icon"?

What is "Gom player"?
What you have done now is to tell Windows that this type of file must always be opened by Adobe Reader. If you want it to open with another program, repeat what you did previously, but choose the correct program this time instead of Adobe reader. All the icons should then change as well.
