If you're not sure how to translate an AppleScript command to the  
equivalent appscript syntax, ASTranslate is your friend:

app(u'System  
Events').processes[u'Preview'].windows.buttons[u'OK'].click()

Error -609 means either the target application unexpectedly quit while  
handling the event, or the command didn't complete within the allotted  
timeout period (which should be error -1712, but the Apple Event  
Manager sometimes returns the wrong code). So does the original  
AppleScript work? If not, the problem is in what you're trying to do.  
If it does, then see if the ASTranslate-based translation works.
