Scheduled ssis insert row

I am trying to use SSIS to simply insert 3 rows into a table daily. The package executes fine in VS. When I try to schedule the package it errors out with a privilege error. The package owner has full rights on the table. The SQL code has been working in a DTS package for years.

insert into tasks values(
        'Daily Change','Noel',convert(varchar(10),getdate(),101)+ ' 12:00',0,
            null,null,convert(varchar(10),getdate(),101)+ ' 11:30', convert(varchar(10),getdate(),101)+ ' 12:00', null, null, null, null);

insert into tasks values(
        'Daily Change','Noel', convert(varchar(10),getdate(),101)+ ' 17:00',0,
            null,null,convert(varchar(10),getdate(),101)+ ' 16:30', convert(varchar(10),getdate(),101)+ ' 17:00', null, null, null, null);

insert into tasks values(
        'Daily Change','Noel', convert(varchar(10),getdate(),101)+ ' 10:00',0,
            null,null,convert(varchar(10),getdate(),101)+ ' 09:00', convert(varchar(10),getdate(),101)+ ' 10:00', null, null, null, null);

Any ideas??

Here is the entire error message:

If you scheduled the package with SQL Agent, the package is running under the login of the SQL Agent, and not the package owner. You need to give the SQL Agent's login the necessary permissions.
