How long, did you wait, before "force quitting"...?
5 minutes or more
I've also verified and repaired permissions
Pete,
Do try waiting a few more minutes. The first incarnation of VI took a very long time to launch and though more recent software versions have improved this it can still take a long time to start on the first time you launch.(do check you've downloaded the latest VI software version) The launch time is dependent on the size of your VI Library (how many collections are present in the library manager) and the speed of your system.
As a guide I find on a G5 2.5 Dual with 6.5 MB of RAM and fast SATA raid drives with the Symphonic Cube and 3 other collections that it takes not much short of 3 minutes to launch from cold. When the cbe was first released it took well over 7 minutes.
