Search for the TO paid email confirmation link sent to your email address, when you bought it and click on that link. 

I resolved it by the doin the above.

same issue here. Updated chrome and restarted, stupid chrome did not sync , so re-installed & logged in again.

getting the same error (Error: A network error occurred, and the download could not be completed. Check you Internet connection.) on restore. Any help on how to resolve is greatly appreciated.
