I was an original kickstarter supported of PA. At the time, I bought two licenses, so I had a "beta" key and a "retail" key. I had been using the beta key during the development of PA and continue to use it with the UberLauncher and all is well. At some point, it got automatically converted to TITANS (I think). I have only recently activated the "retail" key (my kids finally want to play), but it's PA-only, not TITANS. The "upgrade at 90% off" link takes me to steam. I see that today, Steam has a sale on the full TITANS, plus I can get the TITANS upgrade for $4. I have two kids. $25 ought to get everybody all set up. Steam won't let me buy both TITANS and the TITANS upgrade at the same time. Okay, fine; I'll purchase them separately. So I first purchase the full TITANS version because I figure it will be slightly easier to figure out how to play it rather than trying to figure out how to upgrade an Uber license using a Steam key. So I've purchased it on Steam. But I do not want to install Steam or anything like that. I want to just use the standard Uber launcher and be done with it. The internets (e.g. https://steamcommunity.com/app/233250/discussions/0/666826069008563510/) say that you can link your Uber account to Steam and you are all good, but that post is über old (hah) and the link to the linker doesn't work. So how do I actually do this? In 2020, am I required to install Steam or can I just use the good 'ole Uber launcher? For bonus points, how will I upgrade my existing retail (non-Steam) PA key?
