When I attempt to deploy my wsp(SharePoint 2007) to my SharePoint 2010 environment I am faced with an error inline with, Version 3 not supported on this installation, which is to be expected, I then recreated my wsp with all the 2010 references, built and again the same thing happened(version 3 not supported on this installation)

After this I created a new SharePoint project, added all the aspx pages in my wsp to the new solution(under site definition) built and deployd, this time it loaded the default.aspx, but it was blank(IE blank, not a blank SharePoint site)

I use the deafult.master page.

Cheers
