See the photo above. After the new patch I attempted to active the alpha as instructed so I could finally play the game. Nothing happened, so I uninstalled and it won't let me reinstall. I keep getting this message. The SD:44 folder also is refusing to be deleted manually! I have full admin on my computer and can delete other files just fine. Help me out here!

Unfortunately it is a Steam issue, it not seems to be directly related to our game.
If you find a fix share it here.

Can you have a look at the folder's security and see what file permissions are set?

Can you delete the file through an elevated command prompt?

Also what happens when you run Steam as administrstor?

Had this issue earlier, seen several suggestions such as running steam in administrator mode and trying it.
Personally I fixed it by attempting to delete the game, it claiming it had done so on steam but the folder clearly existed still, and then restarting my computer. Upon reboot the folder was deleted and I could reinstall the game without issue.

It's a bit of a pain but trying what I did might be worth a shot?
