Make sure you have deleted the MM2008 assemblies from your bin folder if they are copied there. Also just verify the assemblies are correct in your references and that all references in web.config are correct. One other thing to check is occasionally in the individual pages source, the tag regerences get added to the top of the pages. Just take those out as you should only need tag prefix in your web.config. After all that is correct, build your solution and see if that goes away.
