Tuneup Fails to start

I have a valid subscription to both Security and Tuneup.
1. Tuneup: 
I continue to get popups asking if I want to subscribe (Tuneup) despite Tuneup being installed and activated. The app fails to start says " Oops this was embarrassing". I open My Subscriptions and low and behold, the Activate and Install button is up again next to Tuneup.
I uninstall and reinstall Tuneup, activate it and then it works again for a time but resorts back to the same errors after a few days.
2. Why does my SpyBot find anomalies yet every scan with AVG says I'm all clear.
