I\'m not sure I fully understand your question, but I\'ll answer as best as I can.

Everyone should run the updater before they play a new session of CB. However, most of the bugfixes will happen server-side, which means you won\'t have to download anything when a bug is fixed. The exception to this, of course, is when someone finds a client bug/exploit. Then everyone\'s client will need to be fixed, thus everyone will need to run the Updater in order to do this.
The server won\'t allow you to connect unless you have the latest client version, so if you find yourself unable to connect, try updating first and foremost.
