I had an email exchange with Michael, who seems to be the founder of Wavlake, to help me with this issue. I mentioned that I could not upload another track, and he asked me to send the track image and some screenshots of the problem. After that, I mentioned that I was using a VPN because Wavlake's authentication server is not accessible from Iran. Could my VPN be the reason for the problem? He did not respond to me, and today, when I tried to upload my track again, I noticed that my account had been disabled and my track had been removed.
