I have the same problem in MAC OSX Ableton Live 8.0.4 the Brass doesn't show in VST list,
I think they are not answering this issue because Brass version 2 is on it's way, then you know as usually, you will have to pay for this upgrade & this problem will be solved in Version 2 for sure,
this is what we get used to in all softwares company, hope after reading this they will reply, sorry about being Dark like this, but ask yourself is this what is happening these days or Not
