Today i tried again after a long time to use the update functions in the addon dialog. Sometimes I have to work with a proxy server (with username and password) and unfortunately it never works until now. I remember that you made some modifications to the update process with proxy server but it doesn't works. And today furthermore, as I wanted to cancel the process with the "Abort"-button, it results in a complete crash for the texted application. I sent you the crash report via your emailing option.
Maybe you can keep an eye on it. It would be excellent if the updating with proxy will work someday

Thanks and Bye,
HarryH!
