I found a solution. As it turns out, the CSS class has changed. Below are the steps I used.
1. Go to the “Write options – Page” section in the Adminimize plugin settings page.
2. Scroll down to the end of this section where you can see the two text areas that says “Your own page options ID or class”
3. In the first text area on the left, type in any name – for example type: Add New Page Btn
4. In the second text area on the right type in .page-title-action (this is the CSS class)
5. Press the Update Options button.
6. Go to the “Write options – Page” section in the Adminimize plugin settings page.
7. Check mark the user levels you wish NOT to see the Add New option you just added.
8. Press the Update Options button.
If you are logged in as one of the user levels check marked, click on the Pages menu to edit and you will no longer see the ADD NEW button. Hope this helps others : )
Big Thanks to Frank Bueltge for writing such a GREAT plugin!
