App won't work

After installing Norton 360, one of my exercise apps will not work Im wondering if installing  the Norton 360 would be the cause of this? I have checked with the apps help desk and it seems there is nothing on their end. I installed the antivirus program on my tablet. Any help would be greatful. Thanks

Are you having this difficulty on a PC or your tablet? If the tablet, what make, model, and OS version are you using?
