I thought it would be diskimage file as in .dmg that contained the driver.
Can you see anything inside that .sea file if you Control + click it. Is there an Open package contents ? If so what it inside it?
Update: If there is a problem with Stuffit, you could try this app'
the-unarchiver
and see if that performs the job on that file correctly.
