Hewoo! So you changed the tempo and it was the same thing, right? First start by importing the midi into your utau, go to the file window, than press import. After that you're going to set the tempo to the right song's tempo by changing it in the yellow bar with the 50000, than you pres ctrl+A, click with the right mouse's button and then go to property. There you will press the button clear, set the intensity to 100 and the modulation to 0, set the BRE, consonant velocity and STP to 0 and erase the 0 value right after you do it. Where is lyric you put the hiragana version of "a". After that press ok and tell me what happend. If this doesn't work so put a download link to the midi and I will try to help you from here! ^^
