No, it's okay, I already tried deleting and reinstalling the previous version and now the game doesn't run on 0.90.11 either, and at least on .30, it seems like it got corrupted somehow, and screwed up my progress. ;(
I recommend saving your progress files outside of the game every now and then. Some versions tend to corrupt saves, so it's always a good idea to copy your saves outside of the app.
