Ahhh...much different problem. Sorry for the misunderstanding. :)
I have had several problems with opening several 5.1 projects in 6.0. If you
can't figure it out, send it to the Revit support team and they will take a
look at it and convert it manually for you. You may lose a dimension or a
constrained element, but they will tell you what element ids were affected
by it. Otherwise, if you look at the element ids that it brings up in the
error dialog, you can remove the constraints form those elements yourself
and if that doesn't work, remove the elements themselves, then replace them
in the new file.
