I downloaded the Operation Desert Storm addon yesterday and tried to use it with a clean install of WOV with the Oct 08 patch, and guess what?? It works fine and I have to say the modders really did an impressive job scripting the campaign missions giving it a real authentic desert storm experience. Taking off and landing in a Tomcat/Harrier on carrier after completing a mission has always sold me!
There were however a few minor issues that needs to be fixed in order for it to work with WOV. Here's what i did:
1) Do a clean install of WOV
2) Install the Oct 2008 patch
3) Install the Operation Desert Storm (ODS) addon
4) Download and install the A-10 from the downloads section (to obtain the A-10.lod and cockpit files, dunnoe y they were missing from the ODS addon)
5) Download and install the Icon Replacement (optional)
6) Start the game and enjoy!!
