When trying to startup either 11.5.1 layout or modeler, I keep getting an error message. These problems did not start until the installation of 11.6(as a separate installation,not an update). The message is in the PCore Console and consists of the following:

Traceback (most recent call last)
File "lwPython". line 1.in <module>
File "lwsdk\_init_py".Line 10.in <module>
File "lwsdk\pcore.py. line 177, in <module>
File "lwsdk\pcore.py. line 193, in LWRootNode
AttributeError: 'module' object has no attribute "LWRoot_panel_get

I can close the dialouge box and everything seems to work ok except for importing .3ds or .obj files.(See earlier post). Anyone have any ideas other than contacting tech support. I will do that if I can't get a resolution here.

Thanks in advance
