If you have exit-ed BSPlayer in a normal way, settings should still be there as far as I know. I don't use WinLIRC myself, so can't check for you. Settings should (at least that's what I think) be in file BSPlayer.xml in BSPlayers installation directory. Open it with Notepad and check if there's anything inserted between <WLIRCcodes> </WLIRCcodes>.
