miGraineMarlene is not available anymore. There's a video wich has the link of that instrument. But did'nt work.
This was a very old ensemble (2004-2005) from the Reaktor User Library. Everything in the User Library are made by users, not by Native Instruments, thus each creator may delete his work if he wish. That's why it is always a good practice to download what we like and keep it safe in our disc. ;-)
I am sure that you can find hundreds of newer and better ensembles…
