Problems managing future flights

Hi everyone,
I've got flights to LAX in May, but I'm having lots of trouble trying to manage my flights on the FC website.
I've tried to add my flying club number to my booking on my laptop, on my work laptop, and on ipad, all to no avail.
The help from the FC call centre suggested that my operating system might be to blame, I have windows 7, windows XP, and the latest apple ios. On all systems, I have real difficulty getting through to the right screen, I normally get a "Internet Explorer can't display the webpage" message, and even if I don't get this, the info I've updated does not appear on my booking.
Could it be possible that my FC account has a problem?
Has anyone got any suggestions on what I might do?
I can always just ring up to add the details I guess, but I'd much rather input myself and I'm worried this will affect my ability to select seats or check in online.
Thanks for reading!...
