Pro Import AE 4.0 is needed for After Effects CS3

Are you a user of Pro Import AE 3.0 or an older version of our After Effects import plug-in? If you are and you're moving or have moved to After Effects CS3, you won't be able to use your existing plug-in.

Older versions of Pro Import AE are simply not compatible with After Effects CS3. Only Pro Import AE 4.0 works with CS3.

You can upgrade to version 4.0 here: http://www.automaticduck.com/piaeup/
