Problem when saving .docx and .doc file

[oleg_z99@mail.ru]

Good day!
Our company is going to purchase your product, but in the process of testing Free Spire.Doc for .NET there was a problem:
when you save some .docx files (document.SaveToFile (fileName);), they are truncated by 30 - 40%.
When trying to process the same files, but in the .doc format, saving does not occur at all (the message 'The requested operation cannot be performed for the file with the associated section opened by the user appears.')
What determines the appearance of this problem? No additional actions are performed with the file, only:

using (Doc.Document document = new Doc.Document(fileName, Doc.FileFormat.Docx, password))
document.SaveToFile(fileName);

Hello,
The message 'The requested operation cannot be performed for a file with the associated section opened by the user.' appears in Visual Studio when you try to save the .doc file using the SaveToFile (fileName) method.

Hello,

Thanks for your more information.
I am afraid it is hard to locate the cause of your issue without your original input file. And how about your testing result when using our latest commercial version? If your issue still occurs after testing, please provide your input file to help further look into it. Thanks in advance.
