I did restore the backup; however I have continued to try different fixes. I have found that even if I upload a simply .aspx file it fails to load. I have called my hosting company and they have confirmed that for some reason which they are currently investigating the .net is not working. It may just be a coincidence that I was upgrading at the time the sever went down. This has yet to be confirmed and I will keep you posted.Thank you for your quick response.Best RegardsRoger
