SQL Server: Error and Usage Report Settings

I am using SQL server from previous 2 years. Today I wrote one query for getting some useful information but when I executed this query, then I received the below error. After executing this query MYSQL is not working.
Any one tell me how can I remove this error. I don’t want to do an installation again.
