Blockland won't start anymore

[FF Ryan]

Just recently I felt like playing Blockland again so I got on and a bunch of stuff was missing like.
missing main.cs
missing base/client/defualts
missing base/server/defualts
And stuff like that. I redownloaded and it still didn't work. Can someone guide me on how to fix this.
