Did you try emailing support? I doubt anyone here will be able to help you.

That said, I'm not sure support would be able to help you, as it'd seem like a great way to enable people to steal another's license key.

If they've had so many email addresses over the past few years that they have absolutely no way of knowing what email they possibly could've registered under, but, somehow, still have the password, my guess is that there's very little that could be done, from a security standpoint--at least, by you.

If support has the means to verify the actual purchaser's identity with the actual purchaser, they might be able to assist them, who could, in turn, help you, but, like I said, helping you gain access to the license key that you have no official affiliation with would seem, to me anyway, to be a pretty big security issue.

Either way, there's nobody on this forum that could do anything for you. You'll have to contact support, who, most likely, will probably tell you to have the purchaser of record contact them, assuming vMix is transferable in the first place.

I assume that's what they were referring to when they said it's "restricted", as that's the wording of the "error" message.

When you try to login with the license key on an account that's set to use email/password instead, you get the message



That's almost definitely what they're referring to.
