Are you sure you replaced your old ones with the new ones?
Caus these syntax stuff looks like A5 or even prior.
(create is ent_create, play_entsound is ent_playsound ...)

To update from 6.11 to the latest version:
Download the 6.31 update first (at the very bottom of the download page), install it, then download the 6.40 update and install it aswell.

I don't use the templates and have no idea.
If you have a templates related question please post it over in the Templates forum.
