EndNote X4 Not Working

I’m currently using EndNote X4, but after downloading it into my computer and installed it, it doesn’t seem to work. Microsoft word does not have the EndNote tab. And it is listed under “Disabled Application Add-ins” 

Can someone help me with this??? EndNote is really important to me. PLEASE!!!:cry:

Have you tried activating the EndNote applications via MS Word’s “Add-ins” feature as described in this thread.

I have, but it doesn’t work.
