Geopak cross section error: [There are no Cross Section Cell to process...]

I recently made a minor tweak to an alignment design.  At this point I re-ran pattern lines and was going to re-run the existing ground cross sections when I received the following error message:  "There are no Cross Section Cell to process with regards to current settings" while using the Draw Cross Sections from Surfaces tool.  

My cross section file does populate with the correct pattern line locations and coordinates/elevations but no existing ground line will run.  This confirms that it is pulling accurate (but incomplete) info from both the pattern line DGN as well as from the TIN.

I have checked and double checked that the correct information is filled out in the tool box (dgn with pattern lines, pattern line info, TIN, etc) and everything is as it should be.  

I have made no changes to my MS or Geopak versions in the last year+ and I had just successfully run existing ground cross sections last week with the previous version of the alignment (with all of the same file names and input information). 

As a test after I started having this issue, I was able to successfully run existing ground cross sections on a different segment of the project that had a different TIN model so the program(s) themselves are working fine...  

At this point I'm drawing a blank as to what the issue is and any help would be much appreciated.
