Are demos crashing for anyone else?

Tried playing a .dem for some freinds tonight, and it would play for a few seconds before TF2 crashed. Is anyone else having this problem?

I guess it's just me then. Anybody know how to fix this?

Usually whenever there's a big update, previous demos become unplayable.
