Help, my Bridge does not works well with my AfterEffect. does not preview .ffx files

Hi,

     I have some problem with my Bridge. When i browse preset from my After Effect in Bridge, it won't preview all of the After Effect preset(*.ffx), but my Bridge works well with photoshop files, it will preview all the photo files inculding .PSD. Does anyone knows what's the problem? Anyone knows how to fix it? I need help to fix this problem to get my work in AfterEffect, it is very hard to get things work it won't preview the preset. Thanks.
