Well, you have to try again until it works... But check before that you have got the right files for the update (they are only available in your PreSonus account) and that you have the corresponding software. Here is some useful information: http://www.presonus.com/support/downloads/StudioLive-24.4.2.
Also check your connections (cables, firewire) and electricity.
