Thank you TIG for taking the time and replying my question! And also BIG THANKS to you for all your plugins!
I couldn't stand it anymore and so I decided to reinstall the whole damn windows 10 because my system showed all kind of funky behavior. I suspect there was something fishy going with visual C++. I don't know I am not that splendid computer expert.
I have reinstalled SU and fredo scale and it's behaving nicely, let's see how long that will last.
Have a good evening!
