4/C Before you Begin unavailable on TIA Videos

[Spook]

I am trying to view the Before you Begin for 4/C on the http://www.tiavideos1.com/ site, but they aren't there.
There is a few introduction on http://www.theinfiniteactuary.com/?page=exams&id=4 and a hint of a video with a Study schedule, but they do not exist on the mirror sites.

Thanks for letting me know. I usually don't check the backup sites myself, and assumed all the videos were copied over.
