My web browser reports the "load: class Client not found" error
The load: class Client not found error can be caused by a number of different problems. Usually, this problem indicates that your web browser has downloaded/ cached an invalid copy of our chat software (cache instability or an error in download). Minor network glitches between your computer and our servers can also cause the problem. The problem can be resolved by emptying your browsers cache (or Temporary Internet Files), then shutting down all instances of your web browser, and trying again. In rare circumstances, a reboot may be required.
