I've been trying to waitlist for business class CX101 on 16 October 2016 but I keep getting an error message "There was a system error. Please try again later. If the problem persists please contact our eService Centre. (4002)"

I don't have the required 45,000 miles in my account (there are on transit from AMEX) but I believe I don't need to miles to sit in my account to waitlist, right?

Anyone else experiencing the same problem?
