*Disclaimer... this SHOULDN'T cause problems with your Itunes. If you do everything right, it will be fine.
1. Itunes (duh)
2. A computer (either mac OR windows, separate instructions for both)
Mac users go to step 6...
Step 1: Windows Instructions
If your computer is a Mac, use the OTHER instructions. (skip to step )
First off, don't have Itunes running whille you do this. You can, BUT you'll have to restart Itunes in order for this to take effect.
Just to be safe, close it anyway...
Now, find the ItunesPrefs.xml file.
Usually (in Vista) this is at
C:\Users\YOUR USERNAME HERE\AppData\Roaming\Apple Computer\iTunes
In XP, this is at
C:\Documents and Settings\YOUR USERNAME\Application Data\Apple Computer\iTunes
Replace YOUR USERNAME with your computer user name (duh)
The application data folder is usually hidden in windows so you'll have to type this in the explorer bar.
The folder looks like this-----------
