HELP!! My fable the lost chapters game won't update! And it "quits unexpectedly"

My fable game is having problems every time i play after a few minutes the game will "unexpectedly quit" so after doing some research i noticed a lot of people had this problem. I have not downloaded the update 1.0.1 yet, so i went to do that from feral's site, and whenever i launch the download installer, (multi-language installer?) it says "please insert original fable : TLC disk, it must be present to update." Well i have done that and it won't work, i keep getting the same message! i have restarted, redownloaded the installer, taken out the disk and put it back in everything! Please help, i just got this game and i really want to play it!!
