compatability of rev stacks and livecode stacks in a standalone?

[Mike Bonner]

Just realized you rebuilt the part with the engine with 5.5.2  (yes mike,
reading is a good first step)

you might check in your LC preferences and see if the checkbox for
"preserve stack file versions for stacks saved in legacy format" is not
checked. If it is, go in and manually "save as" to change to the most
recent stack file version.
