Strange, that log contains no indications that the bot crashed. You can try the following in order: 1)A clean install of rebornbuddy 2)Make sure all antivirus are disabled, or preferably uninstalled. 3) Some versions of windows 8 come with a version of .net that has some issues with rebornbuddy, so try uninstalling all the versions of .net and then rerunning the wizard to get the correct version. 4)Hardware issue, make sure all your drivers are up to date and you can try running memtest+ Other then that I don't know, its really rare to see the bot crash and not leave any trace of it in the logs as that usually means its an issue with something outside of our control.
