Hi coderanger,
the launcher crashed (ie. hung) today on my system, it has never done that before. I think this is what I saw: "Unable to authenticate:"; followed by a retry countdown; after a couple of seconds, Win7 popped up a dialog "Das Programm antwortet nicht mehr" (something like "Program doesn't respond" - I guess you'll know what I mean) and offered me to find a solution for the problem on the internet.
I've seen the "Unable to authenticate:" message before, it seems to indicate there's a network glitch during authentication, but I didn't notice the retry countdown before. Not sure what caused the hang, perhaps you want to investigate if other people report similar problems. Since I couldn't force the authentication to fail, I could not reproduce the problem.
I'm using Win7/64bit, no special UAC settings.
