I had to install a new hard drive on my desktop and when I reinstalled Stream and TSW I had basically lost my identity as well as all my seniority points. Guess there is no way to recover them. My Stream achievements are intact.
Unfortunately your progress is stored locally on your hard drive - I am away from my computer so I am sure another will be able to tell you what directory to back up if you still have access to the old drive.
Your progress is stored in / documents / My Games / TS2Prototype / Saved / SaveGames The file PP_yourname.sav is the file that contains all the progress and points. The steam achievements are independent from that profile, even if you start a new profile in TSW your steam achievements will continue.
Thank you Daniel, I had backed that drive up to an external and was, with your guidance, able to retrieve that file and load it.
