Hi Chris,
i have used 7z, it`s free, Google for it. it is much better than win rar.
First un-zipp it with 7z and than convert it to wave, with foobar 2000, than to flac and than you can rename it.
I gotta go out, right now, but will be back in 2 hours, so if you still can`t make it send a mail to me so i can send back We Transfer to you.
