I was able to restore SSIQBACK.DLL followed this procedure:
1) Add Softrak/system folder to Windows antivirus - (excuse this folder).
2) Disconnect all internet and windows antivirus(in registry or settings.
3) Load up clean SSIQBACK.DLL again in Softrak system folder. Test your data if
Backup is working.
4) Re-activate your antivirus and internet.
Still working for me.
