I was experiencing the same issue with not being able to launch.
Oddly enough, when I deleted page 3 from the kneeboard to fix that crash-causing glitch, I was able to launch again without issue.
Coincidence? Maybe. But the result was uncanny.
In the last two years, I've missed the gym maybe a half-dozen times.
I've missed twice this week. This module's going to be directly responsible for me getting fat.
