Ok, another clue, trying to narrow down the genre a bit, I'm going to say the mix I heard is best categorized as a Florida Breaks style track.
It sounds similar (in genre) to the tracks in these mixes:

If you took the melodies I posted and try to imagine them in that genre, and throw in the female vocals you'd be amazingly close. I wouldn't be surprised if the artist is already represented in one of those mixes with a different title (I never did know the artist of this one, only the track name).
