Connect Points AutoLISP

Recently upgraded to Civil 3D 2015 from 2013 but am having trouble using one of my most used AutoLISP commands to connect a string of points (connectpts)

When I load the command I get the following error message;

"; error: Automation Error. Problem in loading application"

Any ideas out there?

Pretty sure had same problem last week and I had to do a Repair on CIV3d, it does not find the AeccXuland version properly.

Just run the version part of your code as a check if it errors then Repair required.
