GUI Texture resolution problem.

Im in need of serious help please…completed my game for my final project at college, put it on a cd and played it on another computer and all of a sudden noticed that the GUI Textures are not where they were meant to be.
Ive search and found that I should have used a form of scaling but the GUI scale script does nothing…any ideas?

Appreciate any help.

This is the Link to the page I found the GUI scale script…
GUI Scale Script

Quick fix: Run the game at the same (or similar) resolution and aspect ratio as you did in the editor.

Proper fix: search Unity Answers, this has been asked (and answered) several times before. There are even several identical quesntions listed on the right, under “Related Questions”.
