I have upgraded my sql express 2008 intance to sql enterprise 2008 R2. But I face issue with maintainace plan.

When I say new maintainance plan I could not see pop up to name "new maiintainace plan".

IF I select Wizard option I Could see the Wizard and create backup Db maintainace plan but then could not modify it.
