No problems - it's easy to miss things in the flurry of troubleshooting
There's nothing wrong with either MBAM or SAS - so long as you don't have them running real-time in the background at the same time as MSE. I routinely install MBAM and MSE on all computers I come into contact with, unless told otherwise, and never have a problem - but I use the free version, and don't activate the Real-time Protection offer.
Like you, I rely on the Windows Firewall - which is quite good enough for 99% of users (and most of the rest should probably be either supervised or behind bars<g>)
Let's hope the settings 'stick' this time!
