I'm using XP64 and can't seem to get reflektor into Guitar rig while in Cubase se3. It's odd because if I run the stand along G-rig, Reflektor is present and can be used. However, if I close it, start up Cubase se3, load in G-rig, everything works but Reflektor is not present. I would think if it's not XP64 bit compatible, then it wouldn't run in the stand alone version either. Any thoughts?
