If you are still experiencing issues with version 1.6.2 crashing on start up please try uninstalling and re-installing from the market--especially if you were running from the SD card. Feel free to e-mail us directly if the issue doesn't go away.
If you get to level 9 and can't go on to level 10 it's because you have not earned enough cheese. Go back and complete the earlier levels in fewer moves and level 10 will unlock.
