I try to upload using Uploader, but it always turns like this:
"Error connection to Server: The remote server returned an Error:(417) Expectation failed" . I did install Microsoft .NET Framework version 3.5, but it still failed.
The problem is not with your Internet or the components the program is using but with the server's connection. That message states that the server didn't respond properly. You might need to contact the server administrator or check the connection settings.
