A bit complicated, but: I had HS3Pro running on one computer, on which Way2Call would not work. I had HS3 standard running on a second computer (HP Elitebook), where Way2Call worked fine. Today, I transferred HS3Pro to the HP Elitebook. I copied the addressbook.xml from HS3 standard folder to the corresponding folder for HS3Pro (Data/Hsphone). The file is there, but when I open the HSphone address book, there are zero entries. Would appreciate help with this one.

EDIT: SOLVED. HS3 needs to be exited, before transferring the file.
