PC reboots but Grimefighter does not run

I had the problem of it Sedated/Contacting HQ for hours/overnight, and never progressing, and I had to force shutdown. Found this forum and read several of the GrimeFighter threads. I also looked at FAQ, and somehow found my way to this statement:

If you are using GrimeFighter for the first time on the computeryou must purchase a license or sign in to your Avast Account to activate an existing license.

After I logged in it ran quickly, all the way through to the end. And yes there was an option to edit the changes it wants to make.

Just purchased today. Installed, license is good. Re-booted several times, always back to windows. I’ve wasted too much time. I’m going to request a refund. Extremely disappointed. Avast software constantly prompted me to run scan and then purchase software. Finally decided it seemed like a good idea only to waste time trying to get it to work.
