For WebForms use this line in replacement to the existing one(first or second line in your html):

%@ Register TagPrefix="mm" Namespace="OakLeaf.MM.Main.Web.UI.WebControls" Assembly="Mere Mortals Framework Web Forms, Version=1.1.1158.18447, Culture=neutral, PublicKeyToken=A16649D902B008D4" %

>It sounds like you went from version 2002 to 2003? If not, then there should be no change needed. If so, the only change you need to make is to your ASP.NET pages. Unfortunately, someone on the ASP.NET team thought it would be a GREAT idea to store the version and public key information in each page. To change this information, open your Web page in design mode and click the HTML tab at the bottom left of the IDE. At the top of the HTML, you'll see a reference to the version and public key token. Just change this to the new values and you should be in great shape.
