I have Windows 10. MEP 2013+ has been working at an acceptable level, although not at an optimal level since I installed in on a previous version of Windows. Yesterday, I experienced a problem with the orange frame marker (line) not scrolling when "play" is pressed (didn't work on MEP 17, either). One suggestion I always find with just about every problem is to reset program to factory defaults, so I did. Now, I the program is stuck on the initial pop-up and can't get past "loading setting." I have uninstalled/reinstalled MEP 2013+ already.
