Problem Running SSIS From C#

I am having a problem running a SSIS Script from within a C# program. Script was running fine and then one day it stopped running and is giving me the following errors and nothing has changed.

2007-07-18 14:27:52,098 [1] ERROR reporting.Processor [(null)] - Problem with DTS Script

2007-07-18 14:27:52,895 [1] ERROR reporting.Processor [(null)] - {Microsoft.SqlServer.Dts.Runtime.DtsError, Microsoft.SqlServer.Dts.Runtime.DtsError}

The SSIS runs fine from the process on my machine, from SQL Server on my machine and from SQL Server on the server. But when I run it from the C# executable I get the above errors. This process also runs other SSIS scripts and they all work fine. I am using the following code to execute the script. Can anybody give me some ideas on how to troubleshoot this problem.

Package package = app.LoadFromSqlServer("\Maintenance Plans\SCRA2", "ppntt240", "load_abc", "bcp123", null);

DTSExecResult result = package.Execute();

Variables vars = package.Variables;
int rowcount = Convert.ToInt32(vars["count"].Value);
String rowcount2 = "0000000000" + rowcount.ToString();

string fullcnt = rowcount2.ToString().Substring(rowcount2.Length - 10, 10);


if (result == DTSExecResult.Failure)
{
Console.WriteLine("Task failed or abended");
log.Error("Problem with DTS Script");
log.Error(package.Errors);

}
else
{
Console.WriteLine("Task ran successfully");
