The only "splash screen" Hijack shows is a little popup window that lasts maybe a quarter second. You should still have the waving penguin behind that popup window, and the popup should disappear well before that penguin stops waving.

*unless* you somehow changed the boot-up logo to be the "Rio Digital Audio" logo which means that you somehow changed the logo area of flash. Using tfabris' logo editor you can change that and get back to the waving penguin.

Hard to tell from your message exactly which predicament you're in though.
