You will have to find your own way a bit on the place to put this 
becasue there are so many places we all install older versions of dod these days.

But basically...

1. You need to find the dod\sprites folder of you dod 3.1 install

2. Choose what size cross you want... see the "DoD 3 1 Xhairs\Other types non dynamic" folder of the download.

3. After you have chosen the size, Copy the file dodcross.spr into that sprites folder you made.

Sorry i cannot make it more easier than that :)


Cheers

INsane.
