Opening forms from a button Addin for ArcGIS 10 on a 64-bit Win7 computer

I recently upgraded my laptop from a 32-bit Win7 operating system to a 64-bit Win7 operating system.  I have ArcGIS 10 and I am developing Add-ins for ArcMap using Visual Studio 2010.

On my 32-bit computer, I had no problems opening forms from any type of add-in. Now when I try to open a form, ArcMap immediately closes and I get the error screen that asks if I want to send the error reports to ESRI.

Here is what I am doing:

Dim myFrmMain As New frmMain

Does anyone have any ideas as to why this does not work on a 64-bit computer?
