Could you be a little bit more precise about "a few months"? I hope you have an enough old chat log file to provide this information
Well, since 2.51.68 (released on Nov. 1 '03), Plus! uses month name in localized language; in other words, directory names such as "十一月 2003" are used. Chances are, I wonder, Plus! couldn't obtain those localized month names from Windows and therefore it could not archive the files.
And by the way, you did sign in before changing those settings, didn't you?
