How 'bout a slightly friendlier title, like "F-25 Help!" or something? With this one, you're just asking to be flamed.
That said, what version of F-25 are you using? V.1.5 is supposed to be pretty good, but it doesn't seem to be available here on the Ambrosia site, at least not last I checked. Supposedly it's on the MacAddict 46 CD, if you can get it. Other than that, try sending an e-mail to the author, politely asking help.
