The file format changed somewhere in there, but I think it was with
version 2.0. At any rate, it didn't affect opening the file. The only
difference was that once saved, you couldn't open the stack with a
previous version. So this shouldn't be the problem regardless of when
the format change occured.

Not sure about that. Since you are getting such weird results, I kind of
think there is more wrong than just the controls themselves. So this
probably isn't a way to debug. It sounds like the file format itself is
I second the suggestion to make sure you have zipped the stack before
moving it to the PC. I have often seen corruption happen when stacks are
emailed or copied without compression.

No, any stack can be opened by any engine. The restrictions are entirely
on the authoring end. The stacks themselves hold no information about
which license authored them; they are completely portable anywhere.
I'd say try the zipping thing and let us know if that works.
