I bought and installed a full version but it still says it's a trial version.
There are two common causes for this problem:
1. You installed the full version while the trial version was still running and ignored the message to restart your computer.
2. You downloaded the full version installer to a folder which still contained the installer for the trial version and then ran the trial version installer again by mistake.
If you have this problem:
1. Press Ctrl + Al t + Del and start Task Manager. Look on the applications tab to see if the program is running:

If it is, click the "End Task" button.
2. Open the folder you
downloaded to and check that you are running the full version installer. All
full version installers start with "setup" and all trial versions
start with "install". For instance, if you have both installers
for the Spartan standard edition, the full version installer is setup_spartanhd.exe
and the trial version installer is install_spartanhd.exe.
We suggest that you delete the trial version and make a backup copy of the full version.
