maxstart isn't generating startup file

[vanderloo]

I've had my material editor set up with all vray materials by default and saved as maxstart.max in my scenes folder and it's been working fine until now. For some reason now when I start a new scene or reset, I'm not getting my maxstart UI. All materials are arch & Design by default.
But when I go into scenes and open maxstart.max directly, all materials default to vray as they should be.
What am I missing? Is there somewhere else I should be saving maxstart.max to? I'm in max 2016 and VRay 3.20.01
Thanks

Chances are your project folder isn't the default 3dsmax folder right now, so it's looking in the wrong place for defaults. My guess.

That would have been my first guess too but how do I determine where to save the file to. It's worked fine up until now.
Thanks

If I'm not mistaken, it will look in your 'scenes' folder inside the project root.
