Run-time error after converting from Office 2003 to Office 2010

[tmStuder]

I have a fine that I have been using since 2007. Yesterday we converted to Office 2010 and now some macros are not working. I get the following error:
Run-time error '-2147417848 (8001010)':
Automation error
The object invoked has disconnected from its clients.

When I debug is breaks here (the red text is highlighted):
ws.rows("2:2").Copy
ws.rows("3:3").Insert shift:=xlDown
ws.rows("3:3").EntireRow.Hidden = False

I have searched and searched and can find nothing helpful. This code runs fine in both Excel 2003 and 2007 but blows up in 2010.

Please help I think I'm going crazy!

I just don't understand why this one broke. I have used that exact same code at least 100 times and this is the first one that had issues.

That being said, thank you very much you have saved me for today!
