KS3 locks up when applying material...pretty much useless right now.

[tcast]

I'm having a problem with my newly installed KS3 (32-bit) on a Windows7 computer. I can't even use it right now it crashes right away. 

When I open a new file, exported from Alibre, it works fine until I start applying material.

Here's the log file. when I open KS.

(11:43:08) QGLShader::link: "Vertex shader(s) linked, fragment shader(s) linked.
"
(11:43:08) QGLShader::link: "Vertex shader(s) linked, fragment shader(s) linked.

(11:43:08) QGLShader::link: "Fragment shader(s) linked.

"
(11:43:08) QGLShader::link: "Fragment shader(s) linked.

These lines show up right away in yellow.

When I apply a 2nd matl. the Fatal error happens and it locks up these lines light up in red and KS's cpu usage goes to zero and it locks up.

This is running on a brand new quad core Gateway computer with an  AMD A6-3600 APU w/ Radon HD graphics  4G Ram.

I've applied the lasted update but it doesn't help.

Anyway to fix this?

Is there something I need to "allow" on W7 in order for this to run?

Does it happen with all models? Can you share the model with support? Are you running the latest version of KS3?
It could be a graphics driver issue, but that would typically happen at the very beginning.

Spoke w/ our salesman over the weekend and it seems to be something with the Alibre exported files.

When I export the file in an .sldasm, it doesn't crash. 

Sent the files to him too.
