First time TT User - purchased the Home and Business for my spouse and I. We installed and did about an hour's work and THOUGHT we bookmarked our progress but we can not find it and are prompted to start over when re-opening the program. 

I have an account which I used to purchaser and download the software  but when I signed in online it again does not recognize me and wants me to start over including re-purchasing. 

Has my progress been lost? If I restart do I have to complete in one sitting as I am unable to bookmark/save?
