Well, it kinda worked. I was able to completely remove USAF, but now when I reinstall, it says it cannot copy a wav file called pa_gsh008 and then if I continue with the installation, when I start the game it says dll missing. When I check the directory of USAF, theres only half the stuff there should be there. I guess my only option is to do a complete reformat. Tried the installation from XP and Win 98 non worked. If anyone else has this problem and was able to get it worked out please let me know. What the hell si a .dll anyway?
