Importing new songs ERROR

[Shingi]

Don\'t know exactly how to enter my own problem separately so I am using this avenue. Sent couple of messages to MTU earlier but so far no reply.
My problem:
Am an elderly gentleman very into Karaoke and purchased Hoster in Sep 2016. Had some songs that I initially uploaded from a portable hard drive. Built up my inventory and moved it to the video file on my PC. I screwed up by deleting the existing data base (from Karaoke data file) and downloaded another set of software from MTU. Of course, now I know that whenever I add songs to my songbook, it gets updated at MTU and whenever I downloaded a \"new\" software, it comes with the data initially loaded by me.
Did talk with an MTU CS but could not fully understand the technical requirements that I need to follow.
My question (and hope): Can my purchased software be cleared of any prior data and be downloaded just like the first time? At least I was able to do the initial load before. I just want to do this one last time for my own collection.

Thank you for any help
