I am using TWS version 831.4 which will no longer be supported after September 16, 2005. I have been unable to upgrade to TWS version 851 without losing all of my pages and settings (what I wind up with is the default workspace and no option to go back to my pre-upgrade workspace). I have tried saving my old settings files and replacing the files after the upgrade to TWS 851 but I still get the default workspace when I open TWS 851. I also get a bulletin board message after updating to TWS 851 saying my workspace is out of date and I need to update it. This sucks. I have many hours and days of work in my TWS pages and settings and I do not want to start over trying to manually recreate them. I have learned from my past upgrades to TWS to clone my hard drive before the upgrade so I can go back to my exact previous TWS if the upgrade does not work which leaves me with TWS 831.4 for now. I would appreciate any help from IB or other TWS users.
