How to reinstall Draftsight?

I need to uninstall and reinstall Draftsight.  I had the misfortune of being gone for a day and another coworker updated to V1R2.0 and then did a restore point on my PC  when they lost all my customizations in Draftsight.  Now  when I uninstall and reinstall there is no toolbars on the screen.  I just want to remove Draftsight  and start over .  I tryed to use the link in my Emal for V1r2.0 but it does not ask for an Email addy to send the link to, it just acts like an update.
