All the sudden my sim won't play the guitar.... don't know why.

I still have that issue on a larger scale. I tried everything. Restarted the game, repaired the game, changed the instruments changed position, debug my sims. None of them would play. It won't even Que. Every time I try to practice and instrument it just resets the sim. The only instrument my sim can play is the piano where she has maximum level at. Other than that nothing would work. This is beyond strange. Pls can anyone help me :(((
