Thank you all for all of your support and time..... The problem is solved now.... :)
I have copied and pasted the missing files into the folder that the error was mentioning. And refreshed the browser and it worked....I have also done the setup according to
http://www.codeproject.com/KB/aspnet/IIS7ASPNet.aspx
that's an awesome thing to follow.....but more or less they say the things that others have said as well.....
I have one more question though.....if I modify the codes now.....as they are converted to VS 2008, will be be usable in the older versions.....or when I upload in the real server?...... When I was publishing/converting the web application, it said that it won't be converted to the old version anymore....does that mean it'll become unusable in the older version as well??? cause the server runs the older version which I can't change.
Thank you.
