Sorry for the delay in getting back, you probably have it figured out by now?
In your animation tab, have adjusted your Range start end, to match your movie start movie end frame? this may be your issue?.
Im using version 4 and im on a mac, im not sure where the Adobe Common folder is? When you say AE you mean After Effects plugins? Because all the plugins are in here? Any other ideas thanks Emmet.
In the color channel in texture select the drop down tab select edit – animation, down the bottom you can change the movie start frame, just adjust that.
