please read first the questions and answers below.:

I cannot access the Twixtel:
Install the Twixtel over again with the appropriate Setup program.

The AddressBook remains hung in the task list and cannot be maximized anymore:
The Fenster6 file was damaged. Delete this under c:/programme/ips/fenter6

Update data from old AddressBook versions:
The AddressBook is downward fully compatible, thus you can simply select the file with the old AddressBook data and access directly the data .

Names of addresses from another program:
Simply export the data from the old program in text format (ASCII). If your program doesn't have ASCII format, take another and open the data first in the Microsoft EXCEL. Save the data in the text format (ASCII). This file can be imported now in the AddressBook.
