I just installed the Lame encoder and it says that the .SGU file is not recognized. I also have Audacity and it doesn't recognize the file. It seems to me that the .SGU file, which is native to BIAB is the issue.

The strange part of all of this is that I just converted my windows OS from XP to 7. In XP I could export as a .mp3 file all day, everyday but I cant do it at all on W7
