I had tried to move the front box and it wouldn't move, but now I see that you can just move the back box. Duh!
This is the same error message that happened the first (and other) times that I tried to convert the data, and there wouldn't have been any V9 files at that time. The error message says "Conversion failed to complete. Error occurred when checking existence of the GL fiscal years data file". My data integrity check has no errors.
I got a lot of info from the webinar, and hope to begin using V9 soon.
I installed the update, plus the most recent service pack, 080402.
