If you have version 0.7.2, your game is up to date, and if the icon is green to the right of the version number, you have the "Forbidden" patch, which makes the game completely free and barrier-free. You'll be able to hit on your mother, tease your sister and some characters will be underage!

There are no errors on this version. It works perfectly. If you have any errors, it's because you're using a savegame prior to v0.6, so you'll have to restart a game. From v0.6 onwards, you no longer need to do this, and you can simply update the savegame with a click to continue the story.
