I just downloaded Mental Ray 1.5. I am running Maya 4. I loaded the Plugin through the plug in manager and it sees it. However....When I click the load button...it will not load the plugin? Confused? How do you fix this?
Maya.env has something to do with it?

The MR for Maya plugin will only work for 4.5 and future versions of Maya. You will have to download new versions of the plugin from AW for each new version of Maya as it comes out.
