i have the same issue - no access to my steinberg account.
did not receive any password recovery email either.
My elicenser CC shows all my licences for Cubase 5.5, WL7, Arturia, Wavelab LE8. and even going through it (Registration / register all…) my steinberg does not recognize my username nor email.
i am considering upgarding to Cubase 8.5 but without access to my account would that be possible?
i can upload my USB key number if required by moderator.
please help me out with this mess.
best, brane
