### CoppeliaSim crashed when I open it

Hello,
Today, When I open the CoppeliaSim Edu, it showed :
"Simulator launched, Welcome!
Leaving..."
on the bottom dialog, and then it quitted. I've tried to uninstall it and install again, but it didn't work. What's wrong with it?

I also meet this question. Due to some reasons, I must use the version of 4.1.

But I find that new version of 4.2 can use and old version of 4.1 cannot use, I also hope that there are some ways to solve this problem .

This is happening to me aswell. Is CoppelliaSim forcing updates or do they have an internal-kill clock?

"[CoppeliaSim:error] This release of CoppeliaSim Edu (V4.1.0.) has expired.
This release will now stop working."

This makes CoppelliaSim appear very untrustworthy.

PyRep states it is incompatible with CoppeliaSim 4.2.
