Crouch animation (new player animations)

I've recently got the source to compile, so I've been adding a bunch of new things. I followed the resource at http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=4348 And i think i've got it working correctly. The player changes between the 3 states. When you go into the game, the console gives some warnings that it cant find the new animations, so far, so good. So I went ahead and made a crouch animation and saved it out as a .dsq file.

I added the line sequence30 = "./player_crouch.dsq crouchroot"; to the data/shapes/player.cs file. However, If I change this file, the player doesn't play any animations, and the console says that it cant find any of the animations!

Is there something else I have to do?
