Adding a Page to section causes TOC error

Question

I have the following document with the section and page setup:
Front Cover - pg A  - Section : letters, start at 1 (A)
Inside Page - pg B
About Page - pg i - Section: roman numerals, start at 1 (i)
TOC page - pg ii
Desc Page - pg 1 - Section: arabic numbers, start at 1
Desc Other Page - pg 2
Inside Back Page - pg 3
Back Cover - pg C Section: letters, start  at 3 (c)
I got the following function in c#:
private static void AddPageToSection(Document doc, Page page, int pageStartNumber, idPageNumberStyle style)
   Section section = doc.Sections.Add(page);
   section.ContinueNumbering = false;
   section.PageStart = page;
   section.PageNumberStart = pageStartNumber;
   section.Style = style;
I have the following method calls:
AddPageToSection(doc, doc.Pages[1], 1, idPageNumberStyle.idLetters); // Cover page
AddPageToSection(doc, doc.Pages[3], 1, idPageNumberStyle.idRomanNumerals); // About page
AddPageToSection(doc, doc.Pages[5], 1, idPageNumberStyle.idArabicNumbers); // Desc page
AddPageToSection(doc, doc.Pages[5], 3, idPageNumberStyle.idLetters); // Back cover page
When I run the code, it throws the error when it tries to generate the toc:
document.CreateTOC(document.TOCStyles[1], true, book, Type.Missing, true, Type.Missing);
It works fine IF only the cover page is added to the section. If any other page is added to a section, it throws the error:
Error HRESULT E_FAIL has been returned from call to a COM component.
Why is this happening? Indessign is Desktop CS 5 with all patches installed. C# and .NET are both supported according to Indesign Documentation.

I might meet the same problem and spent a day to solve it, i use InDesign 5.5, some indesign files can use the createTOC, and some files just through error in javascript or HRESULT_FAIL in VB.NET, here is my code:
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract;
var doc = app.open(myFiles[i], false); <--- you should set it to true
var myStorys = doc.createTOC(tocStyle, true, undefined, [myX1, myY1]);
the key point is when i open the document with false, the error will happen again with some files, but if this parameter set to true, it's just ok.
Too few information from support person to handle the problem... we have to try the script to solve the problem....
