Help me! Whats this (chopin) piece?

[semme]

hey, i just downloaded a piece, its very short, and its played by richter. i really liked it, and so i just looked up the sheet music. and it doesnt really fit. this guy sais "e-moll" in the beginning. im german and e-moll means e-minor. op 25, 4 has also a 3/4 time signature and is e minor. the only thing is, it is way longer and the notes dont really fit. is it a different version, is it another piece? please help me, i really want to play this peace.
