I know this is going to come up sooner or later, so I just thought I'd point it out now:
When you open Mids' up and see this notification,
READ CAREFULLY.
The notification specifically states, "DO NOT UPDATE USING THE MIDS PROGRAM!!!!"
In other words, "DO NOT CLICK ON THE BUTTON BELOW LABELED 'YES'!!!!"
I know that's already been stated here, but it bears repeating.
