Can't logon to Quicken Account after updated.

Question

After updating Quicken file to 27.1.37.66 on Thursday Jan 6, no longer have access to Quicken files. Spent several hours on the phone with customer support trying to figure out why Quicken constantly asks for my Quicken ID and password even though I can sign in to my account via the web with the correct ID and password. Been a  subscriber since 1985. Never had a problem before in all these years of use until the latest update. Made a Quicken backup prior to installing latest update. Update file goes back to 1995. Really can't lose the ability to open my file. I've done everything recommended by web support and customer support. Any idea what could be the problem?
 Thanks, 
 Mike

I took GeoffG advice and reverted to a previous version. I rolled back to version R36.57.
 See the posts from January 10 above.

I was without service from Thursday the 6th at noon until this morning Jan 10 when I tried to logon and did so successfully. The original technician had told me my issue was known within the tech group, a solution was being worked on and should be completed within 24 hrs. Obviously didn't happen. I tried chat tech support over the weekend. All they told me was these "trendy" problems sometimes take longer than expected. Happy now. All is good.
