Invalid tableIndex error after applying license

I have been working with the free version and the following code for inserting content into a table cell worked nicely:

var table = GetTableByTitle(title);
var allTables = _document.GetChildNodes(NodeType.Table, true);
var tableIndex = allTables.IndexOf(table);

var builder = new DocumentBuilder(_document);
builder.MoveToCell(tableIndex, currentRow, currentColumn, 0);

tableIndex would come back with value of 3.

After applying the trial license, this index changes to 7. I can still verify that it is the correct table, as it has the correct title associated with it, but now the MoveToCell call fails with:

Specified argument was out of the range of valid values.
Parameter name: tableIndex

This error happens even when the index changes.

Thanks for your inquiry. Please note that DocumentBuilder.MoveToCell method moves the cursor to a table cell in the current Section. So, please get the tables of specific Section for which you want to insert content. Document.GetChildNodes returns the collection of nodes from whole document (header, footer and body).

Please use the following modified code to get the desired output.

var doc = new Document(MyDir + "template.docx");

var table = GetTable("Strips", doc);
var allTables = doc.Sections[0].Body.Tables;
var tableIndex = allTables.IndexOf(table);

var builder = new DocumentBuilder(doc);

    builder.MoveToCell(tableIndex, 0, 0, 0);
catch (Exception e)

private static Table GetTable(string title, Document doc)
    var tables = GetTitledTables(doc);
    return tables.SingleOrDefault(t => t.Title == title);

private static IEnumerable<Table> GetTitledTables(Document doc)
    var tables = doc.Sections[0].GetChildNodes(NodeType.Table, true);
    foreach (Table table in tables)
        if (!string.IsNullOrWhiteSpace(table.Title))
            yield return table;
