Welcome to the forum, Gengxin. I’m sorry to hear you’re having problems with SDA. Could you please provide the following information so that I can pass on your report to our SDA team?

  • Exact SDA version
  • Screenshot of the actual error
  • SDA installation logs: C:\ProgramData\Steinberg\Download Assistant\Logs\
  • SDA application logs: C:\Users<USERNAME>\AppData\Local\Steinberg Download Assistant\logs
  • Whether antivirus software is installed and which exactly
  • Any other known firewall, apps or network configuration that might interfere with other applications or network?

Thanks!

The strange thing is a file named C:\Users[myname]\AppData\Local\Steinberg Download Assistant\SDA_downloads.json. File is 9434 long, and every byte of the file is zero.
After i delete everything in folder C:\Users[myname]\AppData\Local\Steinberg Download Assistant, I can run download assistant now. This SDA_download.json may cause the error.!
