When I first installed ADD 10 I had problems in that it couldn't find the config files. I got instructions to reinstall by using the demo version first and then reinstalling the retail ADD 10 over that. That seeme to work -- for a while. But since then, I've had three instances where I fail to get the onscreen text message indicating that Acronis is loading. Each time, Windows XP starts, I rerun OS Selector 10, and reactivate OS Selector. That appears to fix the problem -- but only for a while. A few days later, I have to repeat the process again. I'm not making any MBR changes in the interim. IT's as if OS Selector deactivates itself every few days. I've seen other posts where others have claimed that ADD 10 is too buggy and they're going back to ADD v9. I may have to do that as well -- but that's a lousy solution because it means those of us that actually BOUGHT ADD 10 (instead of using the widely available Warez version) have paid for something that obviously need fixing. Acronis updated True Image several times in several days to fix problems with that product. So, when are you going to put out an updated version of ADD that fixes the installation and auto-deactivation problems?
