Completely understand, but is there any codecs I would need to download to make it available. I believe all required codecs should have come with the software package. Its unusual that a perticular audio editing software cannot import mp3 when I am able to play it in windows and other free editing tools.
There is a way to use the LAME codec in SF, but I do not know how to set it up. I use the standalone WinLAME RC3 UI for options SF's Fraunhofer MP3 encoder does not have.
You could try resetting SF to the initial installation default settings. ..or.. try an uninstall/reinstall using a third-party uninstaller that cleans up leftover folders, registry entries and other pertinent garbage the Win uninstall leaves behind. Revo Uninstall is highly regarded, either the freeware or the pro version work well.
