The error lies in the configuration file.
You have to install 4.02 again with the emergency method (this will also reset the configuration), you can use your custom skin, but you can NOT use the saved configuration file, you have to do the configuration by hand. After you have ended the configuration you can save a new configuration file, to use in the future. If all was done oke all should work fine now.
Hope this will help.
