Why script for Skype stopped to work?

First i have:

tell application "System Events" to if exists «class prcs» "Skype" then
  tell application "Skype"
	send command "SET USERSTATUS away" script name "AppleScript status setter"
  end tell
end if

After some time it stopped to work (i feel, it’s because of OS updating).
OK.

After help from here i let only this:


tell application "Skype"
	send command "SET USERSTATUS away" script name "AppleScript status setter"
end tell

Now it also stopped to work (i guess, it’s again because of another OS updating)

How to make it DO work?
