SMES Upgrade / Development ?

Hi guys does anyone know if this script is still being maintained ?

http://www.scriptspot.com/3ds-max/scripts/smes-super-material-editor-swi...

I rely on it heavily for material navigation but it keeps erroring out on me when using VRay.
I've just lost my entire material category for my scene and receiving errors....
Slate just takes too long, SMES is so easy & fast to categorize and select and apply materials.
Is it possible to fix/improve this script ? I notice there has been no activity from the author for over 3 years and no response to requests.

thanks in advance.
