Hi all,
I have Designer 5, and am keen to buy 6 as it answers many of the nits I have with the original version. However, I've downloaded the trial, and it won't let me open sites I've created in 5. What happens when I click 'Open' in the file menu is either the program shuts down, or I get an error message with the following code: bdf60f4c-f3e1-44e0-8e94-81727609312b.

I would buy this upgrade right now, but not unless someone can assure me that I'll be able to work on pre-existing sites created in 5 without a lot of hassle.
