Sorry this happened right as you start the game, I will try and find a solution.
Did you delete the old file completely, if you ever downloaded Tailor Tales before? You have to delete them, not replace them, and this should be in a clean folder.
Edit: I figured out the cause, it's a loading thing. I will try to fix it, in the meantime, you can hit F5 to refresh after running into the error, until you finally get it to work.
Second edit: got a fix for it. For those that already downloaded the game, instead of downloading the entire thing again, you can download this small text file, then find your www > data folder, and replace it with the one in there. Also, delete all files in your save folder. This should fix it.
