After playing Windlands for already for a while, I went to start up the game and noticed the game was showing as uninstalled through steam. However when I went to uninstall my PC did not have enough space, as that space was taken up by the game files still installed. When I went to check in the program files (in steamapps folder), I found all the game files still there for windlands. When I launched the game through that application file in the folder, it opens up uplay, and says the game is about to launch, but then it goes to steam and asks me to reinstall.

So basically I cant launch the game because its missing, but I cant reinstall it because its still there. (And shows that its installed in uplay)
