Hi Tino,

It sounds like you got 2016 installed so the next step is letting ProSeries know where the data is. I am not sure if you are transferring form 2015 or you are doing a restore. In any case if you are restoring when the program is open go to File> Client File maintenance> Restore. In the set source directory box point the program to where your data is located. Proseries should bring in the files for you.

I hope this helps
