That's what I did after having a disastrous experience with v3. I soon realized the MB just isn't the program I purchased my life time license for. It's grown to complex and duplicates protections I already have licensed software for and have zero issues with.
I wish that MB would produce a light version without all of the complexity or at least be able to disable it and use the parts you need. I have found something along those lines but my life time license expenditure for MB was a waste in the end as I am now paying for the new product I use. My choice of course.
However, I am ever the optimist and will be checking back to see if there is anything I feel may be of use for me in the future.
