problem after update

[Topsie3v]

Hi All
I have since my last update of Microsoft .NET Framework 2.0 Service Pack 2 Security Update for Windows Vista Service Pack 2 and Windows Server 2008 Service Pack 2 (KB974470) aquired a problem when opening one of my regular programs.
I have a message come up as follows:

an error occurred creating the form. See Exception,InnerException for details. The error is: Could not load type ‘Invalid_Token.0x0200000” from assembly ‘System.Windows, Forms,Version+2.0.0.0,
Culture=neutral,PublicKeyTokem+b77a5c561934e089’, at WinReg,My,MyProject.MyForms,Create_Instance_[T](T Instance)
At WinREG,My,,MyProject.MyForms.get_frmSplashScreen()

At
Microsoft.VisualBasic,ApplicationServices.WindowsFormsApplicationBase.OnInitialize,(Read Onlycollection’1 commandineArgs)
At
Microsoft.VisualBasic,ApplicationServices.WindowsFormsApplicationBase.DoApplicationModel()


The only way I can use my program is to go back a restore point which I hae done several times and tried reinstalling to no avail
Does anyone have any suggestions please.
