Help with VOCALOID² Miku

Hi everyone, i just installed VOCALOID² Hatsune Miku Voice DB again and wanted to cover a specific song called "Winter Wrap Up" from *cough*... t-the *cough* My Little Pony - Friendship is Magic-series.

I just started with the VSQ, but I have some kind of problems and can't find any solution.
First of all, I always try to make Miku sing in english WITHOUT any custom database/dictionary. Means: I always type in the phonetics manually and "protect" the notes.
Which looks like this:


Now I have some weird problems:
In the line of the picture the note "is" ("i dz") and the note "-ning" ("i n") from "running" are muted for some unknown reason. If I hold the note with the left mouse button to listen to the single note, the playback is working and I hear the note but when I play the whole part or extract it into a WAVE-file, the notes are muted. I have this problem on a third spot as well with the word "even" ("i" + "w e n") where the "e-" ("i") note is muted. Any solutions?
Also: the word "hoovesies" ("h o p¥ s" + "i s") sounds kinda ugly but "hu" ("h M") doesn't work in VOCALOID².

Here's a VSQ with the first lines (the rest of the song are currently filled with "la"/"ra" ("4 a") notes as placeholder.

hmm ok now i have to look where i can get VOCALOID³ :S My VOCALOID² Miku is an original version btw.

Since it's hard to get a Vocaloid-version without additional voice data, i'll try to get SeeU then. Will it work perfectly if i import a japanese V2 vocaloid into a korean V3 version?

 

hmmmmm okay and is there also a SeeU voicbank by Assign Team?
