You already gave the best suggestion, Dave: Contact Technical Support.
They can help Steve get the most recent version of the program available to him.
Steve,
The "Point Orientation" topic in the current gINT Help file discusses the "Point Orientation Support" option.
It goes into some detail about deviated boreholes.
Steve,
I was afraid of that. Bentley posted an update to the Help file around the end of June 2011. Your build was released on May 9th, 2011.
I will email you a PDF of that topic from the Help file.
