I will do my best for you, although as even TranceAddict.com can't ID this it must be difficult.
Have you checked the tracklist of the set ??
Because I see that the sample is from a set.
Mayby you can find the track in there

Edit:
The track sounds nice
Nver heard it but I want to now
TIP: Listen to the vocal part that starts @ 3:00

mayby will it help
I will try it again tomorrow, because due to the time I can't put up the volume
