Can't join multiplayer servers

[GronallaCon]

Hey guys, I'm having issues with joining multilayer servers like cannot open "Trader_Mesh" or something similar. It has only started today and I'm able to play offline fine. I will put in screenshots. I've also experienced "ENV_MAT_LIB" cannot open error too.

Thank you in advance

There was a client-side update yesterday. Might be that you somehow didn't got that one from steam. If so, then it will most likely resolve by validating your game-cache on steam.
- Right-click Killing Floor 2 in your steam library
- Select Properties and open the Local Files tab
- Click the Verify integrity of game cache button

I tried earlier, reinstalled and just tried to verify cache again and it's still giving the same errors

Delete your Cache folder in Documents\My Games\KillingFloor2\KFGame\Cache (or if you want to keep the workshop downloads, delete all the content BUT the subfolders)

EDIT: OR the server you are trying to connect has modified files, and no redirection server to allow you to download...

EDIT2: please post your Cache.ini file here before deleting (it is Documents\My Games\KillingFloor2\KFGame\Cache\Cache.ini)
