Error trying to view demos

[TizthePiz]

Hey, I'll get right to it.
When I try to play demos I get this error:

Missing RecvProp for DT_AI_BaseNPC - DT_OverlayVars/baseclass
Host_EndGame: CL_ParseClassInfo_EndClasses: CreateDecoders failed.

Any ideas about how to fix this? I'm stumped.
Thanks

I don't understand, what demoes?

[duffers20]

is this when you try and view a demo recorded in cs:s or hl2?

I don't think you can watch any demos now that were recorded before the update to the source engine on wednesday

It's for CS:S, and yes, I have reached the conclusion that the update has rendered old Demos unviewable...pity.
