Creo 3D CAD software won’t work

Hello friends
I have been using Creo 3D CAD software but since yesterday when I am trying to open the program it fails to run due to the quality agent which cannot be run. It gives me the following error on my screen:

You must register the Quality Agent in order to continue running Creo Parametric n Tryout mode, if you do not. Creo Parametric will shut down.
Do you want to register the Quality Agent?
Yes No
I called the tech support to report an error but unfortunately my call was not attended. I thought the support is for 24 hours but unfortunately I was wrong. So my problem still remains unattended by the technical support.
Can anybody please guide me to fix the issue? I'll be really grateful.
Kind regards
