I just love it when people start to hack the ASP pages. You should NEVER have to edit the web pages installed by QlikView to get your side to work. If you have installed all your roles correctly QlikView should work. However, there are time when your base OS has issues that will stop things from working normal.
There are a couple of things that will cause this "Loading Content" . The first thing to check is to make sure that the QlikView IIS application pool is set for .net V4. If not, set it and try again. If that doesn't work then run this command
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i and go back check step one. What happens here is that the framework was installed before IIS was. This command will install the framework components for IIS. This should get you going.
Again, you should Never have to edit the QlikView pages.
