Hello,
My company had bought the CadLib 3.5 suite, and we would like to upgrade it to the 4.0 version that has OpenGl that supports Hatch.
I downloaded your trial version and when I try to open our file with it, I get the following exception:
************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

Your quick help would be truly appreciated.
Thanks
