I cannot answer your question concerning if future updates should work as I'm not a developer.
However, your statement that:
This doesn't make sense? Perhaps you ment to buy the lite version for now then buy the european version later?To buy now the full european version and live in the meantime with the lite.
Currently there is not upgrade path from the lite version to the full version.
I'm not sure what you are saying we don't offer? The upgrade from the lite to the full? If that's the case, we don't offer it now because the lite version has only been out a month, tops. The upgrade bundle hasn't been developed yet. Things like that take time and not that much time has passed since it's been made avaliable.
If you're talking about the European version not being avaliable yet....it's being worked on.
I'm not sure I understand!?
