Can't VPN using Windows client - WARNING: No server certificate verification method has been enabled

I, also, have problems with the Windows VPN.  The first time, I neglected to print off the "instructions" that pop up when the link is displayed (not the BIG link that says "Windows", but the tiny link under that).  So, I had not created the NETGEAR-VPN network link that is required.  I also created problems by renaming some files but not renaming the link to the files that is inside the opn setup file.
