EndNote x3 submenu not appearing in Word 2008 on Mac

We have several users asking the same question regarding the EndNote X3 submenu being missing from the Tools menu in Word 2008 on a Mac.

There is an FAQ solution on the offical website:


However even after following all the steps instructed there the problem remains.

I know that EndNote X3 might have compatability issues with Mac OS Snow Leopard (10.6x). Could this be the cause of it?

Has anyone had the same problem and do you have a solution?

Many thanks.
