Copying a back up

[andy]

Hi
I ave a back up copy of who wants to be a millionaire and would like to copy it. When I try to copy it with adaptec it says that the file is to big, so I copied to hard drive first then tried again then adaptec said that it could not read some of the files. I have alsotried using CDRWin but only made coasters. ny help would be appreciated.
Thanks in advance
