Microsoft Visual Studio There is no editor available

I have recently upgraded my Microsoft Visual Studio 2005 to 2010 version. After converting a program written with my previous version to the latest version of MS visual Studio, I attempted to open a form and got an error message.
I can see the written code without any issues. But when I attempt to open it, in form I get an error.
Microsoft Visual Studio
There is no editor available for ‘C:UsersUserDocumentsVisual Studio
2010ProjectsMBMBAccounting.vb’.
Make sure the application for the file type (.vb) is installed.
I have tried reinstalling the .net framework on my PC and that does not help.
Is there a simple solution where I don’t have to reinstall my applications again?
