Can Execute trigger in SQL2008R2

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 MSSQL2008 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'
