Hi there little Wayfarer

If you let the updater update untill it crashes, you must go to updatertemp, copy the exe there over the main updater.exe and then launch again. That should work.
This only seems to work when you have updater *before* this update though, or else you won't have an updatertemp.
This is still a big issue though as the updater dies *before* it creates the updater.exe on new installs.
