Cyberduck - 3.3b4 and Snow Leopard

I'm a photographer who must send large files out. I'm currently using the most updated version of Cyberduck (3.3b4)...Obviously Cyberduck has not fixed it's problem with Snow Leopard or vis-versa, because I get messages like "Upload failed. Pipe broken" just at the end of the upload, and I have to start over. Is there something else I can use beside Cyberduck with Snow Leopard, or can anymore tell me what I can do to use the current updated version of Cyberduck and Snow Leopard?

Any answer very appreciated.
