Page Cannot Load Web Part : Could not load file or assembly


I am upgrading SharePoint 2007 to SharePoint 2010.  There is a web part that is not able to load.

I tried navigating to the url and going to ? Content=1 but the web part is not their.

I then navigated to the web part gallery and deleted the web part but I still get this error.  Please see the attached screen shot.

Is there a Powershell script or other way that I can use to close this web part? or delete it and all traces of it?
