Hi, My AVG Antitrack recently stopped working. I have a paid subscription with activation key using on only 1 device. All other AVG products are working but anti track now says SUBSCRIPTION STATUS: TRIAL EXPIRED. I try to reactivate by entering activation key but anti track tells me THIS ACTIVATION CODE HAS ALREADY BEEN USED. How do i fix this issue?
