Since the old updater will cease working anytime soon due to Java's security restrictions and there are no free code signing certificates available, I have developed a new version as 'stand alone' Java Application.
http://updater.pala.de/new/
I am currently testing any possible fault condition I can think of, but it is always better to have other people play around with it and try to break it.
Java 7 is required, but the launcher will automatically download a local version to its folder if it cannot find any installed on the system.
The download is currently tunneled through a CDN (updater.pala.de.nyud.net, which is coralcdn.org), because Chrome freaks out about the executable file until Google has crawled the website again.
Please feel free to test it and report back.
