stopping current client

I know there were threads here about the same problem, but nothing helps here. Maybe someone solved this issue. Game worked ok and everything was fine but came a new hotfix that apparently changed a game and made it unrunnable. I can run to the main menu, I can choose some server from the list...

PLEASE HELP ME, i cant join any servers because it just keeps saying "stopping current client" Things i have tried: restarting router restarting computer re installing starmade turning of my firewall logging in again checking my details on the registry (all good) PLAZ HELP MAH!
