Yesterday I downloaded the new Returnil 2011 (the free version). Right after the installation was completed, the computer crashed and I got a blue screen (the computer kept reboot itself with blue screen). Before that I used the old version of Returnil (from 2010) for a long time,and I uninstall it,but the program worked fine with my computer. Only when I deleted the program from my computer on Safe-mode the blue screen disappeared. What is the cause for that thing? how can I fix it?
