No just see if it is checked on the list. I had a similar problem with water bricks and cubes, the main reason was because in v10 badspot made it so there is NO SPACES allowed in the names of files. And my cube brick file was named, "Cube Bricks.zip", so I changed it to, "Cube_Bricks.zip". And I am pretty sure it cleared up the problem. I hope this helps.
