Downgrading gnucash?

[Matthew Vanecek]

Try this: 
Back up your data file (of course, always!).
Open your data file in your favorite text editor
Find the line that says <gnc:book> and delete it.
Find the line taht says </gnc:book> and delete it.
Try to open it once again in your 1.6.x version of Gnucash.
Report results to the list.

I don't know when the gnc:book tag was added, but private emails on
another matter suggest that it was post-1.6.x.

HTH.
