I re-installed web matrix multiple times + i also re-installed my dotnet framework 4.0.
Any help would be appreciated. Thanks
EDIT: I recovered my system to some back dates when it was working fine for me, but still i am facing the same problem.
I have attached screenshot on the following link, please take a look for better understanding.
