Usually I suggest the following when you get a -10:
1) Restart the computer. Sometimes that clears the error.
2) If you’re using iDisk, eject it (whatever the terminology is). Some users have reported that iDisk interferes with the activation.
3) Last thing to do is delete the Users/Shared/Ticket/particleIllusion.Ticket file and activate again at the website. (Do NOT delete the ticket file that’s in the particleIllusion application folder!)
Whenever you activate, record the “request number” and activation code.
