Strange. I downloaded the current build and it worked fine for me (saving included). I really don't know what to tell you :/
Does it give you a crash error message or something? Check your anti-virus software isn't causing troubles with it. Try running it on a different PC, maybe?
Its fine. For some reason the save page (YOMOTSU/www/save) was missing. Its working now and stopped crashing. Thank you very much for you attention. (^^)
