To All Users: Please Close MBM and also close CPUIdle, both use files that need to be replaced with new files. MBM 3.xx users: I recommend you uninstall all previous version of MBM before you install 4.xx MBM 4.0x users PLEASE NOTE that because of changes in the Core Voltage Setup your original core voltage setup is gone, so as soon as you start 4.1x please go to the Voltage Tab > Setup and setup the Core Voltages to your personal needs.
