This evening while opening SR-2, I got the little black box that signaled an update was coming in. Somehow, after loading the game, I was back at version 9.307. How that happened, I have no idea. Where and how do I get version 9.5 and the latest beta? I've gone to the Steam website, but can't find those two versions. Where on the Steam site are they located. Understand, I'm 70 years old and I need a very step by step explanation of how to do this.
Okay so when you open steam itself and go to the simplerockets 2 section in your library, you should find a button in the shape of a gear on your right. If you click on it, you must select 'properties'. After that it opens a box that shows 5 options:
-GENERAL
-UPDATES
-LOCAL FILES
-BETAS
-CONTROLLER
select 'BETAS' and select the beta you want to opt into. Then select 'beta-public beta testing'
And thats that ;)
