Knight-Templar, darth_daniel, your are weird problems... I will check if I could find a solution, because at the moment I have no clue...
-Edit-
@ darth_daniel: The metal050.jpg image isn't a default image of Photoshop, I've added that image into my patterns (open the image > Edit > Define Pattern ) If you have added that image into your patterns and it still doesn't work, I have no idea... Or maybe you should "flatten" that layer (you should create another empty layer UNDER the "pattern layer" and merge these two layers).
@ Knight-Templar: The exact name of the tool I've used is "Rectangular Marquee Tool", so, yes it's the "rectangular lasso"
