Hi, in Windows 7, I installed butt 0.1.21, downloaded libfdk-aac-2.dll, put that file in this folder C:\Users\Me\AppData\Local\butt-0.1.21, started up butt, went to Settings > Audio > Streaming > choose AAC+ but it says could not find AAC library. It streams fine with MP3. Any tips what to try next? Thanks.
