Problem with Avid to After Effects

When I arrived back from Easter break I was told that Avid Media Composer work flow to After Effects  is not very compatible, and that it would have been easier to have created the video on Premiere Pro, exported it and sent it straight to After Effects.

However, I knew there would be a way round it but It would take more time. I searched on Google how to do this and followed the steps. I needed to export the video as DNxHD Quicktime for it After Effects as reference, exported the file as an AAF and then when I opened up After Effects I went to 'Pro Import After Effects' and imported the file.

The timeline seemed to come into After Effects absolutely fine. Started to work with the key light, removing the green background and correcting the dancers' saturated skin. I spent about two hours playing around with the green screen and I saved what I had done.

I came back to work in After Effects today and opened up my project to find my work and the timeline in blocks of colour. Notifications kept popping up on my screen so I knew straight away it was something to do with not being able to access the Black Magic files. But I couldn't understand how to fix this problem.

I got help from Peter and Stefan who tried various different ways of trying access the files. In the end it was something to do with the MXF server and because the footage I shot were RAW files. I moved all the files into the same folder and connected to my avid project on the MXF. Every time I edit on After Effects, I need to make sure I open up the MXF server before hand connect to my project.
