Mathcad Prime 4.0 doesn't start anymore.
Hi, I'm using the Mathcad Prime 4.0 free version. The programm was working perfectly fine, but now when I try to run the program it doesn't work anymore. The mathcad logo appears, but then it disappears again and a main window never shows up.
Then if I check the Task Manager, I can see that the program is running in the background.
I already tried to reinstall mathcad but it also doesn't work.
