Microsoft office database engine has stopped

[HIMANSHU]

I am getting the following error when I am trying to save a query.

"The Microsoft office database engine has stopped the process because you and another user are trying to change the same data at the same time."

What is the reason?

I googled the error message you posted and found this:
http://support.microsoft.com/kb/182867
which suggests that your db has corrupted.
Towards the bottom of the page is a link to:
http://support.microsoft.com/kb/109953/EN-US
which gives some advice about how to repair dammaged db's.

Are you sure only you are accessing that access database and there is no body else?
