I've clicked the AACS link and submitted dumps, anything else I can do?

I had this too yesterday, also submitted the dump and awaiting the next update when it's ready in due course.

This is working now, film extracted to MKV. Reported some AV sync issues but on playback the lip sync seem fine throughout.
