Having the same issue. Serial number for H9000R is coming up as invalid when I try to register online. I sent an email to Eventide support several days ago. I tried to call their main office but was informed support is working remotely and my best bet was to email.
I even posted this question on the Eventide Facebook page.
I re-sent my email request this morning. Just looking to get my unit registered. Thanks.
I can take care of this for you and make sure the you can register it to your account. Could you send me an Email directly at email@example.com
Thank you for the response. Somebody from your team addressed it via email. Sorry for spamming the forum.
