The timeseal program is for use with FICS or some of the other free Chess servers. Timestamp is to be used with the ICC server. To use timeseal, open the properties page of the internet console window, check the 'use timeseal' box. Click on the 'Setup..' button, if you installed ChessPartner 4.2 you can in principle leave all the fields empty. To use the timestamp program you have to fill it's program name explicitly in. Fill in the full pathname in the path field. e.g.

"C:\Program Files\Lokasoft\ChessPartner4.2\timeseal\timestamp.exe"

Then in the parameters field fill in: %1 %2 -p %2
