Xbee Cellular 3g Modem Error

I am attempting to make use of my Digi Cellular 3G Global development kit. One problem that I am having however is whenever I try to save a configuration profile I get the following error:

Remote file ‘support/firmware.cellular_modem_xbee_cell_3g/23.50.zip’ does not exist.

Would anyone know why this happens?

Thank you in advance,
