Server connection

When trying to join a server I could join before the update, now when loading mods in the top right it says (you have a unpacked version of [multiplayerbeamnp] Need to be packed before update) in a red box. I tried another server and it loads but the screen is blue and I can see usernames but I am frozen, I can spawn cars in but cant see them and they end up breaking. Help would be appreciated, already uninstalled and installed beamng and beamMp and still the same.

Try clearing cache then or go to safe mode and return to regular beamng.

Sounds a lot like this: BeamMP loading undermap/underwater
Which server is it?
Move the camera above the water and spawn a car.
