DreamWeaver

I download concerts on the web that come in either .flac. or .shn file formats and can not fiind a cd burn software that supports these files. I have tried Nero 7 Lite but to no avail. Could not get it to run. I have also tried FlacFront end but was confused on how to use it. I have seen that Winamp supports these files but did not see where it is compatible with Vista or not....I am using Windows Vista Home Premium OS. Can anyone help me out here and give me directions on how to do this and what to use. I know there must me a sharware or purchase program out there that would do this??? Thanks!

When after installing Nero 7 Lite ver:7.11.6.0 on Windows Vista, I get an Error message: "problem accessing registry-HKEY_LOCAL_Machine\software\ahead\Nero-Burning ROM needs full read write permision", when I try to run the program. How do I correct this?
