If you're having trouble patching, please try downloading and running the installer again, as it will update you to the latest version.
Neronix: if you still get the error on patch.xml after installing from the updater again, check the log file again, and it should show what address its seeing for proxy configuration now. Let me know if it turns out to be blank or set to something. I'm not using any strange api's, just the standard web download interface.
