Default [Q] Google Search Music Extension don't work

I've made a complete reset of my Xperia z duo a battery drain and now it's gone... But I have Google search music extension fk... I use it very much and I need it...

until now I've cleared the App's data - I uninstalled it and they install it, I made the same with the Walkman app - nothing... I updated to Google services 5 - still nothing... Help!

I'm with Stock rom 4.4.2 with root... The bloadwere was deleted... Thanks in advance....
