Contact details renewal problem on Toastmasters

I am Hing Yu Yeung (Member Number: 6936745), Vice President Education (VPE) of UWA College Row Toastmasters Club (Club Number: 05755035, District 17, Area N22). I registered to Toastmasters using my old email 21801622@student.uwa.edu.au last year. Starting from this year, I have updated BOTH my "primary email" and "previous login" to my new email hing.yu.yeung@gmail.com

However, when I am trying to contact my members by sending email to members-5755035@toastmastersclubs.org using my new email, the system kept on popping back stating that:
You do not have the right permissions to send an e-mail to this e-mail address (members-5755035@toastmastersclubs.org) from hing.yu.yeung@gmail.com . Be sure your "From" address in your e-mail client is the same as your address in your toastmastersclubs.org member profile.

In addition, when other club's officer want to contact me via members-5755035@toastmastersclubs.org it is my old email receiving his/her message.

It seems that my new email address has NOT been updated into the system, although I have updated this via Toastmasters International's Club Central.

Please kindly reply who I shall contact to solve this problem. Thank you.

You need to update your email address on your club website. If you know your password you can do that by logging in and editing your profile, otherwise you'll have to ask your club website administrator to help you. You aren't currently listed as an officer on your club website, so any email addressed to vpe-5755035@toastmastersclubs.org or officers-5755035@toastmastersclubs.org won't get to you
