OK, Since this is for a Trail version, I can help you. (If this was for the full version, I'd suggest at their site, or if you didn't buy it, you get in trouble for breaking the rules here.)
Right Click on the icon then the menu item "Run as Administrator" and see if it works.
If that works, you can set this up for a more permanent solution by Right Clicking on the icon then the menu item Properties. In this window, under Compatibility Tab, Check "Run as Administrator."
I found that under Google, with just the word "nTitles."
