Please help, I can't change any of the settings in ms dashboard (i.e. date and time, language, etc.) and I need to change the date and time in order to save some of my games. Can someone please help? I'm not sure if having evolution x installed, effects this issue? Everytime I click on the time/date option in msdashboard it freezes. Please please help!

try recopying over your backup of C

how do I do this exactly and will it negetavily affect my xbox at all?
