" Server running an old version of the game "

[Hydrogena 1]

Hello everyone,
This isn't the first time this has happened to me, but I haven't been able to connect to the Zombie Revival server for three days because it asks for an "older version of the game." 

What should I do?
I don't understand.

hello hydrogena,
You should check your "Properties", then Beta of css in your library.
It should be "None"

Thank you very much, I didn't know!
