Obviously they have a problem with the updater...but they seem to want to direct blame at user error, or servers not having all the required files at the time of live update first pass.
What to you mean with "obviously" ? Since the only TWO possible reason for that message, we can only indicate both of them, which is exactly what we did:
1) The user having inadvertedly disabled GSX from the menu ( the "Disable" entry is close to the Settings entry, so it's possible to click it by mistake. In fact, we are considering adding a separator line... )
OR
2) Servers not having all the required files at the time of live update first pass.
If your wasn't case #1, then it was #2 so, clearly the Live Update never had a "problem" to begin with but, like anything server-based, it *depends* on what it can find on the server so no, the Live Update doesn't have any problem, and it WAS an issue of the servers, which is not really something we can have full control on.
