I would start the program all over again, that way you get the sensation of a new beginning and won't worry about the possible 'lost' effects of the program level you had already completed. It's kind of like any other process; begin again so that you train yourself to be disiplined enough to go through the routine in a different way this time so that you can complete it and reach your goal. Find a better time for your practise or a better place so the 'life doesn't take over' and have you stopping again.
I would, first, though, take some reflection time and think about why it is you want to begin again, where you may have 'gone wrong' the first go-round, and to think of new strategies that will help you improve upon your re-do of BrainEv. If you had a journal the first time, read it again so that you can 'see' where your focus was. If you hadn't had one, maybe this time you should so that you can follow your path and make the best of it....again.
Good luck to you and I hope that no matter how you choose to go about it, that you just DO!
Have a great day.
Blessed Be!
