Problem in loading Designer Window

Question

Hello Everyone. I would to compliment myself, it's my first time here on this forum.
So... I'm having a problem in Visual Studio.Net 2013 and I don't know how to fix it.
It appears when I load the "designer" mode in Visual Basic or C# projects.
I'm stuck here, it's the first time this problem appearing to me.
I can't post my printscreen yet in the forum because of verification of my account, but here are the errors...
1º- The file "c:\... Menu.cs" does not support code parsing or generation because it is not contained within a project that supports code.
2º- Load of property 'RootNamespace' failed.
3º- Load of property'AssemblyName' failed.
4º- Load of property 'DelaySign' failed.
5º- load of property'FileAlignment' failed.
6º- Load of property 'DebugSymbols' failed.
7º- Load of property 'Optimize' failed.
8º- Load of property 'OutputPath' failed.
9º- Load of property 'DefineConstants' failed.
10º- Load of property 'WarningLevel' failed.
11º- Load of property 'IntermediateOutputPath' failed.
I will wait for your instructions.
My regards

Hi Edward :)
Forgot to tell you that I have Update 4 of VS2013 Express.
About the errors, It happens when I create a new project or if I load a old project.
One of the projects is a winform in Visual basic( I created from the start, so it's a new one) and the other is a console app in C# which I created months ago also with VS2013 Express. When I created this c# project there were no warning errors.
I tried and create a new console app in visual basic but it also shows this errors in the beginning:
Error- 'Sub Main' was not found in 'testapp.Module1' 
2º-Error - Type 'testapp.My.MySettings' is not defined.
3º-Error -    'testapp' is not a member of '<Default>'. 
The 2º and 3º error refer to a file Settings.Designer.vb
Namespace My
<Global.Microsoft.VisualBasic.HideModuleNameAttribute(), _
Global.System.Diagnostics.DebuggerNonUserCodeAttribute(), _
Global.System.Runtime.CompilerServices.CompilerGeneratedAttribute()> _
Friend Module MySettingsProperty
<Global.System.ComponentModel.Design.HelpKeywordAttribute("My.Settings")> _
Friend ReadOnly Property Settings() As Global.testapp.My.MySettings
Get
Return Global.testapp.My.MySettings.Default
End Get
End Property
End Module
End Namespace
I renamed the form as you said with the project loaded but the design view still not works.
I can do a streaming of when I create a new project, so you can check what is wrong with this...
