VS2005 - I cannot add a new web form, master page, web service, etc - object reference...

I am unable to add a web form, master page, etc. in vs2005. When I try it I get "object reference not set to an instance of an object".....

I have uninstalled framework, vs2005, sdk - still same problem. It happens even if i create a new web site - i cannot add any pages (but the default.aspx shows up)

thank you.
