I have a UFX and i'm having some problems loading the snapshots and workspace from one computer to another

I have 2 macbook pro, both have the latest software version of totalmix and the only difference is that one has thae MAC OS leopard and the other has the snow lepard
if i save a snapshot or workspace in one of the computers and send the file to the other i can't open the files ... I can open the files that i save in the computer i'm working on and can't share files between the computers ... any ideias?
