Office keeps shutting down

I recently installed Leopard and since then I am having problems with Mac Office 2004. I keeps shutting down unexpectedly. I have reinstalled the app and it still occurs. Is there a patch or idea on how to fix this?

Launch word, go to Help, click on check for updates.
Mine works fine on Leopard. I have to use it for school.

I can't even get to the Help menu. It freezes prior to that then quits.

When you reinstalled office.... did you just trash the app or use the uninstall tool?

I just reinstalled it. How do I perform a clean uninstall? I am new to the Mac.

Insert the Office disk, look for 'Uninstall Office' or similar, uninstall and then do a clean install./

As soon as it is finished do an update, which should start automatically. The last update is November this year and entitled 11.3.9.

Office, Word etc work fbne in leopard.
