472538 Registration Form Bug Fix

Hi, I'm trying to sort out a registration form script where by users can sign up on my website to access free and paid templates. The script I'm using has two choices, either the user PAYS for membership, or the user can sign up for FREE. Everything is working if the member has to PAY. But if I choose to have users sign up for free then that's where I get a problem. When users register, they fill in their details and click submit, they are faced with a confirmation page, which works fine. But when they click Proceed, they are faced with a blank white page! I was wondering if someone could have a look at this and fix it for me! You of course will be paid for the work! the website link is here: [login to view URL] the sign up page: [login to view URL] If you try you should face the same problem!
