Lost inventory on game restore.

We have a pretty decent size community that has started playing this game, and we have been playing on a friends normal game instance. She logs out and it boots everyone off, so I set up a server on a local machine. I had her back up her storage folder, and restored it. I renamed the two saved files to game.eco and game.db. The game loads fine, but when I log in the storage is in crates, and 4/5 of it is missing. Any ideas what I can do to move the data over to a standalone server without losing most of our storage?

One thing I didn't do was move the configuration files over, so could that cause a corruption?
