applescript editor will not open

Please help! I’m rumming OSX 10.3.9 and suddenlly my script editor and all of my scripts wount work any advice?

Could you ellaborate a description? Eg: What does it happen if you double-click the Script Editor? Have you tried using a third-party script editor, as Smile? What does it happen if you run this in a Terminal window?
osascript -e ‘beep 2’
Have you repaired permissions? Have you deleted the AppleScript component or mangled something in your root System folder? Etc…

Do you have multiple sign-on onto the machine?
