Quote - So, if it's at 3.7, where are the updates for those that have bought Pro before?

All updates are FREE for FS 3.1 Pro and FS 3.5 users (you can use the same key as before).
We currently released a DAZ Studio plugin, which will be followed by the standalone version within days.
You will be able to download the free app at www.abalonellc.com or maybe even here at Rendo.
