Bejeweled 2 Registration key?

We got this game from the flea market brand new and never opened. It game in a box that read Bejeweled 2 and was purchased from staples 10 dollar shelf. We go to install it and that works fine but then when we get to play it it tells us that we only have 45 min to play it unless we bought it. well we did buy itt brand new from the flea market.. does ANYONE have the registration key that WE cna use to play the game? this is for my mother on her computer and shjes very frusterated and says she refuses to pay extra for something she just boughtr for 5 dollars.
