AntiTrack keeps telling me that it is about to expire

I bought this service yesterday(I bought premium) and my AntiTrack keeps sending me pop ups that it is about to expire and that I need to buy it again, which interrupts whatever program I have running. However, when I click on it and run it it works perfectly, without saying anything about it being about to expire. Is this a bug, or what is going on with the system? How do I stop getting these notifications?
