Blank property box in Visual Studio 2008 Professional

[DeSmOnD dAvId]

When I try to make a new project in Visual Studio 08 Pro, I am unable to set any properties for the form because the property box is blank. I tried in VB as well as in C#, but the problem is the same. I tried to check Tools>Options and under Windows Forms Designer, here too the page is blank with the message "An error occured loading this property page". I use .net framework 4.

Please help...
