When trying to install AVG Tune-up I got a statement that Tune-up could not be installed due to an incompatibility.  When I wrote this to AVG Help I could not send the problem write-up.  A red statement popped up on the screen: "fill in all fields", but all fields were filled in.  Who can I talk with to resolve this?
