I can not see any external player anymore

[Mir Mira]

While playing with my xperia z3,using your 0 6 01 version,I accidentaly selected the "always" tab while testing a CRAP stream player.Now I can not select other player anymore. Pls....how can I destroy this BAD,bad,bad association between your software and this crapy player?? N P.S.Tried to delete cache and data for both softwares,uninstalled and reinstalled stb..still no luck.. My phone is not rooted..... I presume some info is associated to my MAC 'cause if I change the Mac everything works again [for a while]...after that my wifi connection breaks! Forgive my bad english and poor skills in Android.

Resolved by re-reading your "instructions" :If application doesn't work after installing VLC plugin, remove folder StbEmulator from SDCard.
