IntelliJ Won't Start, Web Server Stopped?

I recently tried to upgrade by IntelliJ IDEA Ultimate to the latest version. The first time it had the loading screen and it was migrating plugins. After that it closed down and wasn't anywhere to be seen in Task Manager (So I suppose the program closed itself).

I still don't know what might be causing this, here is the log file:
