Library (CFG) Entry

Hi,I hope someone can help.I change aircraft registry CFG's just to make listing aircraft easier, ie, alter the CFG entries so I can have each aircraft grouped together when selecting an aircraft to fly when starting FS.I've done this for every aircraft I have loaded.For some reason if I edit the 767 winglet model it will not show in the 'select aircraft' library. (By the way I'm using FS2004.Below is an entry for the regular non winglet 767....[fltsim.0]title=B767-300ER MYTRAVELsim=B767-300model=panel=sound=texture=mytravelkb_checklists=767LVLD_CHECKkb_reference=767LVLD_REFatc_id=G-SJMCatc_airline=Kestrelatc_flight_number=201ui_type=B767-300ERui_manufacturer=BOEING - LEVEL Dui_variation=MYTRAVELdescription=Boeing 767-300ER, configured for a short haul flight\n\nDry Operating Weight -\t196000 lb (88905 kg)\nMax Allowable TO Weight -\t408000 lb (185068 kg)\nTotal Zero Fuel Weight -\t253011 lb (114765 kg)\nMax Allowable Fuel Weight -\t154989 lb (70303 kg)and this is for the winglet version....[fltsim.0]title=B767-300ER LEVEL D LIVERYsim=B767-300model=panel=sound=texture=kb_checklists=767LVLD_CHECKkb_reference=767LVLD_REFatc_id=C-WLPEatc_airline=Level D Simulationsatc_flight_number=192ui_type=B767-300ER WINGLETui_manufacturer=BOEING - LEVEL Dui_variation=LEVEL D LIVERYdescription=Boeing 767-300ER, configured for a long haul flight\n\nDry Operating Weight -\t197000 lb (89359 kg)\nMax Allowable TO Weight -\t408000 lb (185068 kg)\nTotal Zero Fuel Weight -\t244976 lb (111120 kg)\nMax Allowable Fuel Weight -\t161000 lb (73029 kg)I can't see why it will not show after I've altered it, I have done this for every aircraft from different developers and never had this happen...Any ideas?ThanksAdrian
