8.3? Are you using some sort of beta version? Or are you talking about Pro Tools 8.0cs3?

There are several different methods for importing MIDI from Sibelius; which one are you using? Could you please describe the MIDI session? How many MIDI tracks/instruments?

Having a "powerful computer" and having a "compatible computer" are two totally different things. Posting your complete computer information would help us determine if there are any hardware incompatibilities that could be causing problems for you. Looking at some of your previous posts, it's definitely a possibility.
