try to delete and download it again using your desktop manager,..once you open it on menu option it must display the color option you want to use,(random,disco,or single color)...
All you do is download the zip file. Open up BlackBerry Desktop Media. Then click add program or something like that. Add whatever was in the .zip file that shows up basically. It has a .alx or another ending onto it. That simple. Then follow through with the steps. Make sure you have 4.5 os and your good. You might want to update to the newest version of BB MD which is 5.0.1 Everything will work fine after that.
