old ticketmaster account and tomorrows pre-sale interaction

[jeffs]

I have an existing ticketmaster account with my credit card and other info used to speed up transactions. For tomorrows fan club pre-sale do we completely ignore logging in with that account and go straight to the pre-sale and loggin with our fan club id only. Do we than have a chance to enter all the necessary billing stuff and will our existing account interfere with the fan club stuff? Just got the day before jitters!
