Do you have a Time Machine backup?
Perhaps the only way to get around this problem will be to format and install again.
I purchased DockLock from Ameline systems a while back. I just got a new computer and transferred my files sucessfully. Now DockLock no longer seems to work correctly. It's locked and won't unlock. Ameline systems seems to have vanished from the net. When I try to launch DockLock, it tells me I need Mac OS X 10.5 to use it and of course, I have 10.6. How do I get rid of this thing?
