Can't import mp3+g files

[Jim Brown]

Hey here is the trouble I am trying to import mp3+g files that I have bought and downloaded over the Internet. These files are top hit monthly files i have tried every template available in the convert mp+3 selection i keep getting the message improper template selected. the filles I am trying to convert consist of the mp3 file and the cdg file I have also tried to convert the zip form of these files. And yes i have read the help files on converting mp3+g and still not getting it. any help would be appreciated.
thanks
