If the USAF_Repair_Tool doesnt work, then you need to go in and MANUALLY remove the USAF keys from the regisrty. they are located in :

HKEY_LOCAL_MACHINE
- SOFTWARE
- JANES COMBAT SIMS
-USAF

If you dont have ANY other JANES games installed on your machine I'd recommend you delete the WHOLE Janes folder.

To enter the registry, click the start button, go up to RUN, then in the OPEN box, type " regedit " ( without quotes )

If your a bit too intimidated about going into the Windows registry call EA Tech support and they will be more then happy to walk you through the process, it takes about 10 minutes...
