Hello
One of the reasons may be cheats or programs like: walker, speedhack, artmoney etc. If you have used something previously on other servers and have not correctly deleted, the protection system can be recognized as a potential danger and kick from the server (as the modules from these cheats often get into the game process). Also, the problem can arise because when you start the game and update, the files are updated from the cache (temporary files) of the system or the browser where the corrupted files are located. To solve both possible problems, use the following solution: try to clear the temporary files. you can do it manually or with the help of special programs. you can use the program ccleaner. Download it here: www.ccleaner.com/download. Run the program and clear the temporary files and cookies, temporary files and the operating system cache dns. then reinstall and update the game client.
