Issue:
When you restart the program (after it becomes unresponsive and freezes your computer), the splash screen is displayed briefly and then closes down with no apparent error message.
Solution:
Troubleshoot the problem using the following process:
Verify that the Licensing service is running:
- Access the Windows Run box.
- Type Services.msc and press Enter.
- Search for FLEXnet Licensing Service or FLEXnet Licensing Service 64.
- Make sure that the services are started and running (if disabled they prevent the program from starting).
Make sure that the firewall is not blocking the program from checking the license.
