I would favor the missing links/drive theory -

I have with other cat-settings files that were created on a HES catalyst with an internal secondary drive, and when loaded on to my system, the drive obviously isnt there... (hense the copy on my firewire drive) So once the correct folder path is selected, it works - Although, it doesnt crash every time before the correct folder path is selected... luckily intermittent..!

However, I do have a M-audio Detta Dio 2496 card in the mac that i use with SAMSC - so i'll remove it to see if it makes a difference and make sure i;ve got the up to date drivers. I noticed a lot of log entries in the system logs when i was trying to find out what might be causing the crash... But I dont think it will make a lot of diference - it's only loading catalyst that seems to crash it. (intermittently...)

Will let you know the outcomes (thanks so far....)
