Error when running Tuning advisor

When I try to launch the tuning advisor, I get this error - Any help will be much appriciated.

What is the service pack level on SQL Server?

Any recent changes to the server and client machine you are using, such as automatic updates?

|||Hi,

I had got the same error when I tried to tune my query.

However after I click "OK" button of the Error message, in few seconds the "Tuning Adviser" window opens but it is not connected to the session of the query editor (in which the query was executed).

Now without closing this tuning adviser window, if I again click on Analyser button, the analyser opens fine and the query is also tunned properly.

Let me know if this works for you too.

Regards,

Shweta
