I'm using Tivimate at this time with my buzztv and no issues so far , actually I prefer tivimate because it has the option to see all the servers that you have on one list no need to disconnect and connect to other server ( all the servers are staying connected on one list), Maybe you have other apps that they conflict with tivimate, or depends where you download it from ,try to update it in Google play, i bought mine and I updated in Google play.
