Alot of Black mesa Errors

Hello Black mesa Team.
I decided to play game once again,

I find out that there are some bugs come up in the course of months
Some of NPC are not talking or there are some Lichts error Flikkering.

So i did re-instal mod and Source engine 2006/2007
So nothing work so far

I have save file, but dont know how to uploud it,
so i desided to give hier 1 line of command it was saying.

Failed to load sound “^weapons\357\reload_npc.wav”, file probably missing from disk/repository
Attempted to create unknown entity type !
NULL Ent in NPCMaker!
