Unhappy [Q] Venom hub account bug

I had ROM on my HTC One S, I created an account with venom hub, but for some reasons, I must re-instaled ROM, and I forgot to remove my account? Now, when i use "I have already account", he says me "Device already link" and i can't created another one, and I don't have "Venom" in my account settings. Someone can detach my device please?
