I have been having problems with the program shutting down by it self. You recommended I uninstall and reinstall the program. I did this but the reinstalled program would not accept my serial number I had to install a trial version to get it to work

Hi quaranaa, 

By any chance, did you receive any error message? That will help us look into this. In the meantime, please try activating the software again by following the instructions in here: 

Upgrading from trial to full version of Trend Micro Security

Let me know if it helps. :)
