It's not a problem just a question

Is there a way to exchange the "key/ serial" codes from the ones you supplied in torrent to a bought copy without having to do a complete re-install? I ask the as I am slowly gathering each pack on a one or two a month basis, especially watching for Origin sales. I want to continue enjoying the full game that all you have wonderfully shared to all of us, but as I buy each EP, SP, or world I'd like to change over those codes without losing everything.

thanks in advance for your time and help with this.

I looked in the registry editor and this is what I found:
HKEY_LOCAL_MACHINE\SOFTWARE\Electronic Arts\Sims\(expansion name)\ergc

Or you can redeem it on Steam, it automatically swaps the registry info I think.

Thanks bunches, For the help.
