This can sometimes be caused by issues with a qvw.
Also I note the line before the error says
The document D:\BIDATA\销售主题包\SALES2.QVW was loaded.
First I'd suggest backing this document up elsewhere and then deleting it to see if that cures things. If so then you can look for the issue in the qvw.
Also I have never used a folder named 销售主题包\, What language are these characters? I certainly am not familiar with them, maybe they have confused QlikView as well as me.
