What did not work you did not indicate? nor you have contacted the support team through the support tab, I didn’t see your issue in support threads as well.
Additionally, we had mentioned various times to check the debug log, you must have to enable debug to true in wp-config.php file.
Also, refer to all the steps and mentioned points here for more clarification.

Please do let me know if you want me to assist further.
Thanks
