I would like to express my thanks to Bill Clark. Further investigating brought me to his post on a different thread that solved the issue.
Here’s a copy of his original post.

Re: CS4 Premiere Won’t Encode Videos..

OK, believe it or not, 5 mins after I posted my rant I managed to solve my problem. It had nothing to do with all the stuff that everybody on the web was suggesting about re-installs and clean scripts. Something much simpler. I have a few plug ins on AE – Sapphire, Magic Bullet etc and I realised that every adobe programme was loading them on start up. And I kept getting an error message from Premiere Pro and Media Encoder about Magic Bullet looks – that it wasn’t registered. It was driving me nuts because it is. I reinstalled everything twice, and during this process spotted that Adobe is now putting all the plug ins in a central folder – which it refers to as media core. This on a Mac is at Macintosh HD/Library/Application Suport/Adobe/Common/Plug ins/CS4. (There might also be a CS3 file as well)
It occurred to me that this might be causing confusion – Media Encoder trying to load plug ins that it doesn’t understand and might not be licensed for in the XML file. So I pulled them out of there and put them straight into the AE CS4 plug in folder. Bingo. All the plug ins run fine – AND SO DOES MEDIA ENCODER! And now, no problems at all with the dynamic links between AE, Premiere Pro and ME.
I’m not saying this is the solution for everyone – but it’s worked for me. Hope it helps somebody.
Over and out.
