Issues with Sage 50 Accounts logging on after July 18 Windows 10 update

SUGGESTED

I have just uploaded the Windows 10 Update for July 18 and when I have come to log on to my Sage 50 it is stating that the passwords inputted are invalid.  I have gone through the Compatability suggestions online and its still not working.  I am at a loss as I cannot get on to any of my accounts and it is an over 1 hour wait on the helpline.  Please help!
