Error Loading SSIS Package - CPackage::LoadFromXML Fails

When I try to load an SSIS package via C# code I get the following error message:-

"The package failed to load due to error 0xC0010014 "One or more error occurred. There should be more specific errors preceding this one that explains the details of the errors. This message is used as a return value from functions that encounter errors.". This occurs when CPackage::LoadFromXML fails.
"

The code is pretty straightforward:-

Application app = new Application();

PackageEvents evts = new PackageEvents();

Package pkg = new Package();



Package pkg = app.LoadPackage("C:\Documents and Settings\dominic_s\My Documents\Visual Studio 2005\Projects\SSIS_Util\bin\Debug\DTS\Cleanup_Staging.dtsx",evts,true);

return pkg;

What's interesting is this error message only appear's when I Start Debugging (F5 in VS 2005). If I Start without Debuggging (CTRL+F5) I dont get this error message. I've tried almost everthing suggested by other posts in this forum related to the same issue but nothing seems to work.

Any help will be greatly appreciate...thanks!!!
