I see you haven't linked your Steam account to your StarMade one. You can do that here: https://registry.star-made.org/profile/steam_linkI bought this game through steam.
I was wondering if there was any way for me to verify it and get a full download of it outside of steam?
yeah, but if you download the free version you can not play on servers. On steam i can. i just need a registered version that's not on steam. for my work laptop.The big Downloads button up top can get you a copy of the game as easily as steam can. http://star-made.org/download
