Please check the following steps :
1) Check whether you have the latest version of Emsigner (version 2.7) and have latest Java JRE installed.
2) Please use IE 10/11/Edge Browser as it works for many people and as neither chrome nor firefox supports java plugins.
3) Ensure proper internet connection and check whether any antivirus software / firewall blocks emsigner.
4) Uninstall all previous version of Emsigner and restart the system.
5) Now , Try to upload gsc in gst website.
If any problems, tell me.
