Can Execute trigger in SQL Server 2008 R2

I'm trying to create a simple trigger to update a table's column after it was inserted.

But when I execute the trigger it produces an error:

Cannot execute script. Additional information: Unable to start Transct-SQL debugger. The Transact-SQL debugger does not support SQL Server 2005 or earlier versions of SQL Server. (SQLEditors)

I'm using SQL Server 2008 R2.

Here's my simple trigger just to check if it execute.

CREATE TRIGGER tgrCheckFile 
ON CheckFile
FOR INSERT
AS  
        PRINT 'New Check has been issued'
