First at all, i reccomend you to reinstall Fifa with complete install before using FCDB XP. - I have msg : "Parameter incorect" : Be sure your screen is in 32bits mode. - I get "acces au fichier refuse," when I try to open or save .dbi. : Be sure your dbi file isn't in read-only mode. - I haven't english language : Put Language.lgf in your FCDB folder. I'll edit this post with more info as soon as possible to help you as i can.
