Unable to Restore Retrospect Backup

I am using Retrospect backup software to backup my system for years. Recently I had a problem with my computer. The restore CD doesn’t worked and hence had to reinstall the entire OS and update it. Then I installed Retrospect and its updates. Later while trying to backup, I got the error 1017. I had a research and tried the available resolutions. Now I am able to complete the backup but with error 8000. Then I downloaded free backup software and finished the backup process without any errors. Now I would like to restore the Retrospect backup and on trying that I got the same 1017 error. I have goggled this error and tried the VSS fix as suggested in some forum. But I am still receiving the same issue. What should I do to get rid of this?
