The part of my fliptop that hold the white disc fell off as soon as I opened the the fliptop, is there anyway I can put it back on? When I try to put it back, it just falls off again. is there anything I can do or do I need a new fliptop? Also, when putting in the white disc, do I put it in with the silver part facing out or on the inside? (This is on a v9) Thansk for all your help.
