Sidescroller

So, i'm making a game and i tried to send a file to other coders to help me edit it, but he says he can't "Path does not exist"

I had all the files compressed on a .zip file, it was sent, and then, he tried to use it on Dream Maker but he says it said "Path does not exist"

How am i supposted to send correctly my file?

I used share files with MSN.
