When I want to use the text animation presets I get an error message, an example is when I want to use a text "animate in" preset and got the following error message: After Effects error: Can't import file "Fly In From Bottom.ffx": unsupported filetype or extension. ( 0 :: 1 ). I have check my bridge script settings and they are activated for After effects.
Sounds like you are trying to import a FFX file instead of applying an animation preset. Some users are reporting problems with Bridge. Just type the name of the animation preset into the Effects and Presets panel and apply it from inside AE.
