Single Player off line play
 

Ok.. It''s old but I like DF2 and have it along with the SF upgrade and not sure of Nova has shut down their servers or what but I cannot log to them and several of the Single Player games will not play without being logged online... So I'm stuck with 6 or 7 maps that play in single player and a bunch that will not play and come back a say not logged on... So... How do I play the single player maps without logging into the online server...
