Getting a "Failed to load material" message

[MadCat]

Hi

 

I just add some things to my map and are getting this message

 

Failed to load material "C:/Users/Josh/Documents/Leadwerks/Projects/MyGame/AddOns/SciFi Interior Construction Kit/sektor74587.mat".

Entity mass must be greater than 0.

 

The funny thing is that there is:

 

1. no "C:/Users/Josh" file

2. no "MyGame" file

3. I even deleted "sektor74587.mat"

 

And still get this message

 

Removed the objects I put in and still this message

 

HELP??!!
