Last night I purchased the online upgrade for COMB1 to COMB2. I installed the aria player but it does not pull up on the playback devices menu in Sib 7.1. I also noticed that the COMB2 folder did not contain a sound set for me to put in my Sounds folder. The Aria player does show up on the playback devices menu if I have it running before I start Sib 7.1. It only shows up as a midi plug-in though, and not an AU.
I can't find any info on how to change the Aria Player from a stand alone to an AU plug-in.
