I strongly suspect there are very few Sequoia users who visit these Magix forums. Especially since there is a dedicated forum for Samplitude and Sequoia users here. I think you may receive more helpful replies if you repost there.
However, i do know there have been problems experienced by various users who have recently attempted to register at and post there. I don't know whether those problems have been resolved so you may have to be a little patient, unfortunately.
