Hello, I have a whitelist account to upload files to the FTP server. But my FTP credential can't use when I upload files for whitelisting. I registered ​again, but my request was rejected. ​My ​username is ftp_wpsc​n. Could you please check this credential is normal or not? And let me know how to solve it, please.​​I look forward to your reply.
Best regards,

Dear,
Thank you for your reply.
I have received the email from Milan who is on the AVG Senior Technical Support Team. 
I tried to reply to the email but failed.
My reply is "Please reset the credentials and send us to the email address​ ch****n5@wps.cn."
Could you please tell Milan my reply?
Thank you very much.
Best regards,
Yasmin
