I have disabled Vray from the preferences. Error message doesn't show anymore, but still, I got bugsplat whenever I try to hit Enter (finalize the bending). Thanks in advance

Hello guys, please help me

This is my first time using this plugin and I am having error
ERROR: skpHelperClasses.rb:updateSkpMaterial, curMat is nil

It shows continuously after I click on the Shape Bender icon, it stops when I click on the red-axis line, and it starts to show again after I click the curve. I get to the screenshot I attached, but when I click enter to finalize the bending --> bugsplat!

Anybody knows what's wrong? Thank you very much.

Siska
