Unknown error after compiling [solved]

Hey I really hope some of you know something about this, because I can't find the problem.
Earlier today I added a checkbox and a timer to a fully working project(Black Ops trainer). And I gave them this code:
[highlight=VB.net]Private Sub CheckBox19_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
'esc fix
If CheckBox19.Checked = True Then
Timer6.Enabled = 1
Else
Timer6.Enabled = 0
End If
End Sub

Private Sub Timer6_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)
'esc fix
Dim Esc As Boolean
Esc = GetAsyncKeyState(Keys.Escape)
If Esc = True Then
If CheckBox16.Checked = True Then
ButtonNew14.PerformClick() ' fast trigger
End If
If CheckBox15.Checked = True Then
ButtonNew15.PerformClick() ' 1 shot
End If
End If
End Sub[/highlight]
The code doesn't matter, but the point is that there was no errors.

I clicked build and went into the release folder. I started the program and there was no problem, but when I copied it to the desktop it wouldn't start. It just gave an error.


So it will launch in the bin\release folder but when I move it I get that error.
I tried to find something on google about clr20r3, but I found nothing.

I also tried removing the checkbox and the timer + code, but I still get the error when I build it.
