Just a tip for anyone logging in for the first time.
Use your normal Rangers ticketing number to do the password reset instead of your email address, if like me you have both a ticketing account and a Hospitality/VIP account attached to the same email.
I put my email address in initially and it recognised my VIP account rather than my ticketing account, I assume because it uses the same database as the VIP account.
I've had to go back and do the registration with my normal ticketing account because otherwise it wouldn't have picked up I had the pre-sale access with Ed House membership because that is registered to my normal ticketing account.
