LL Update Problem

[justme2]

After todays update, for which there was no progress indication until the completion window appeared, this is the Update log. Is there any clue in the log as to why I do not get a progress window anymore? Is there a config file for the progress window which may be corrupted, putting the window off screen? Or any other suggestions please?
