Spreadsheetgear Maintains Lock on File

Question

Through an C#/ASP.NET website, I'm using SpreadsheetGear to open a file from a template, then making modifications to it based off user input and then saving it a new location. When I attempt to manually open the newly created file after saving, I get a message stating that SpreadsheetGear has the file locked for editing.

Here's code snippets below:

SpreadsheetGear.IWorkbook workbook = SpreadsheetGear.Factory.GetWorkbook(pathToTemplate);
workbook.WorkbookSet.GetLock();
SpreadsheetGear.IWorksheet worksheet = workbook.Worksheets["sheetName"];
SpreadsheetGear.IRange cells = worksheet.Cells;

//fill in worksheet
...

workbook.SaveAs(pathToGeneratedFiles + exportFileName, SpreadsheetGear.FileFormat.XLS97);
workbook.WorkbookSet.ReleaseLock();

worksheet = null;
workbook.Close();
workbook = null;

The only thing I can think of in the undisplayed "fill in worksheet" section that is even somewhat tricky is deleting a column and shifting the other columns to the left.

Any thoughts? Thanks.

So, it turned out to an old copy of the SpreadsheetGear DLL in my project's bin folder. Once we updated it, the problem went away. Thanks for the help.
