Don't worry about it Ken...
[size=5][red]TO INSTALL[/red][/size=5]
1. Go to "My Computer"
2. Go to control panel
3. go to "mouse"
4. go to the pointers tab
5. double click on the cursor you want to change, it will pop up with a window, probably in windows\cursors, which is where you should probably unzip them to. If you didn't, find the folder you unzipped them to and then click on the one you want to use.
6. Enjoy
*edited to say- this is the way to do it on my computer, using Windows 98 , I would imagine it is the same or very similiar in newer versions.
