I have two computers running the SMP client and when I shut them down last night to tweak the config file (changed cpu utilization from 75% to 50%) they will not restart. I deleted the install and tried reinstalling it but to no avail. Both computers this happened to, changing the settings back in the config file does nothing. One computer is running xp 64 bit and the other vista 64 bit. Do I need to delete some stuff in the registry?
