The only actual updating that happened was Unity updating their web player. I do not know how you could have lost your progress but we recommend using the export and saving the code it gives you to a notepad so you can import it in and restore your data. There is a VERY rare chance of progress loss occurring if Unity web player crashes while our game is in the middle of saving your data, however. Which is completely outside of my control which is why the export is so important. ~Taiga
