Q Was that in downloading/installing v1.7.2, or in trying to use it?
A It was at the tail end of the installation
Does that mean you never got 1.7.2 installed, so the remaining issues such as Sony not showing up were still with V2.0?
I don't think the time issue will be a problem until you get to the book stage, and probably not even then.
As long as computer and Sony are set to the correct local timezone and telling approx the right time, all should be ok.
