I have installed Release 1.2.9 ("The Village Idiot") of cpp-ethereum on a windows 7 machine. It downloaded the chainblock overnight and I experimented with mining this morning. My PC became non responsive and I had to reset my system. After reboot, I tried running AlethZero again but all I got is a console message in the title of this question and a message window informing that AlethZero.exe has crashed (pic below).
Can anyone point me in the right direction for resolving this issue? I would hate having to download a 25GB blockchain again.
