Do/While statements not working in Modeling

I have an automation I use very frequently. I have made no changes to it and have not updated NX, currently version 7.5. However now suddenly the program just cycles away and never achieves anything. I have managed to narrow down where the code is failing. This is a while statement I haven't changed since the first iteration of the program.

   While Not line is Nothing
         If Len( Trim( line )) > 0 then
            Try
               strings = line.Split( vbTab )
               pt1.x = Double.Parse( strings(0) )
               pt1.y = Double.Parse( strings(1) )
               pt1.z = Double.Parse( strings(2) )
            Catch
               MessageBox.Show( "Spline data file " & strFile & " must be tab deliminted," & _
                  " and located in " & strDir, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error )
               Exit Sub
            End Try

            '------------------------------------------------------------------------------------------
            '   Create an array of points, each array value containing a single point
            '------------------------------------------------------------------------------------------

            ReDim Preserve ArrayofPoints( count )
            ArrayOfPoints( count ) = workPart.Points.createPoint(pt1)

            '------------------------------------------------------------------------------------------
            '   Increase count value by 1, Read the next line of the file and continue While statement
            '------------------------------------------------------------------------------------------

            count = count + 1
            line = sr.ReadLine()
         End If
      End While

I have no idea why this is suddenly a problem, any help would be greatly appreciated.

UPDATE: I have tried multiple different Do / While Loops all of them just continue to run without ever accomplishing anything. While in Modeling this is a problem.

However things seem to work just fine if run in Drafting.

Solved, thanks

And what was the solution?

The readline is inside the If check. So when it ran across a blank line it never read the next line of the file.
