Go into config and open up mm.bot. On the top alone it asks if u want to use multiple cd keys, put yes, save, go back to config. Go to mm.multikeys and fill in the 2 sets of cd keys, save, go back. Then do the same thing in mm.playkeys. To set how many games u go before switching, open up mm.bot again. You should see Extra_runsammount = (number of runs to do before swithcing cd keys if u have mroe than one) change that number, save, and u should be set.
