Can't Download KSP after Getting it on Steam

[Bej Kerman]

Not sure if this goes into modded or unmodded, but anyways, here's my problem:

Before getting KSP on Steam, if I needed a new instance of KSP to test mods, I'd go to the KSP website > account > download, then I'd get what I need. In this case, I wanted to install a new instance so I could have KSP with the DMP mod only. So, after getting KSP (no mods) on Steam to make updates and DLC a bit easier, the website thinks I only bought the steam version. But I bought KSP alone in 2013. I can't update any existing non-Steam instance without having to buy the game again, and that's my last resort. What do I do?

Well if you used the option to "transfer" your game to Steam then it will obviously not be available on the website anymore.

You can still use Steam to download older versions and then just copy your stuff around:
