If the BlackBerry is tied to an enterprise server (BES) then it's possible mass storage mode is disabled by policy. Did you open options and look? If so, then there is nothing you can do (except talk the admin, but admin probably can't do anything either).
You do not need to have Desktop Manager running to use mass storage mode. Once enabled on the BlackBerry handset, the computer will see it regardless. But you do need to enable it on the handset.
