Well Kilzo error type 2 are usually memory errors,check your memory and I wouldn't advise on wiping your HD clean than you'd have to reinstall all the crap, maybe reinstall Rogue Spear and delete Gameranger and I MEAN everything that has something to do with Gameranger files. Than check your ip address and your email to see if its correct than download the latest version of GR and try again if it doesn't work well you're in trouble and prolly need to contact Evill or go to a Apple dealer to check your comp
