True Image ran once, now fails to respond on Win 8 system

I'm using a Dell vostro 3300 running Win 8 Pro on a Core i3 with 8 GB of RAM. I initially installed True Image 2013 and successfully activated it, ran it once, and since then it fails to respond. I've tried using the Cleanup utility followed by reinstalling, but every time the initial screen comes up and that's it--no response. In frustration, I recovered the system from the initial backup, with the same result! I'm absolutely stumped. I've been using and fighting with True Image releases since 9...when it works, it's super, and when it doesn't it's aggravating as heck...
