We just updated to of Syncfusion and we started getting a Null Reference Error on our Worksheet.AddCopy calls.  I'm sure it's because we are doing something wrong and it just wasn't causing a problem before.  We do have code that messes around with IName.Delete().  But in the earlier version of XlsIO things ran OK. 

Stack Trace:
Object reference not set to an instance of an object.

Can anyone point me in the right direction as to what we might be doing wrong to cause XlsIO to Exception when we call AddCopy()?  Thanks
