hi! this indicates a problem parsing the game data. what format is your game data in? did you copy the text from the game data window in bitsy, or download a .bitsy file? if you loaded an .html file, it won't work.
if you send me your game data I could take a look at what's going wrong - in the meantime, you could try the old version of pixsy and see if that works better.
I'm sorry there's no error message that appears - I'll have to work on that and make it less confusing.
