Hey Solarint,
It seems the main download (as well as the secondary one linked in the changelog/message) for the 3.0.3 version points to only version for SPT 3.8.3, not SPT 3.9.0.
To get the version 3.0.3 for SPT 3.9.0, I just went to Solarint/SAIN's Github page and downloaded it from there under Release/SAIN 3.0.3
Just a few of the 380 users online
