Construct 2 Can't Open Examples

Few days ago I brought Construct 2 on Steam.

Whenever I want to open an Construct 2 example a Window pops up saying what program do you want to open it with.

"Windows can't open this file:Particle effect.CAPX

"To open this file, Windows needs to know what program you want to use to open it.

Windows can go online to look it up automatically, or you can manually select from a list of programs that are installed on your computer.

What do you want to do?"

I then select "Select a program from a list of installed programs" and find Construct 2.

But it then says fail to open Construct 2.

What do i do? <img src="smileys/smiley5.gif" border="0" align="middle" />

If you right click on the example can you select 'Open with...' and then see if Construct 2 is listed as a program to open it with? If it's not listed, you might have to browse for the program.

I already did that and it says "fail to open Construct 2".
