Hi,

Although I cant really help you I did try to download your file and it ended up corrupt and unopenable.
I can give you this tip, if all your sounds are in library folder, make a copy of your file and delete the sounds library before you upload, I imagine this will make your file more like 100mbs instead of 480mb.
With the sounds missing it should not be a problem or so much of a problem when editing the file, when all is good put the sounds library back in, or just copy and past the code from the edited file to the one with the sounds in.
