This was the reply I got from the mod distributor.
Thanks for your comment first. I know this mod is different from traditional mod of bf1942,because of its mod-active mechanism.that is only for copyright protection,and is free for the first users.
Some files of bf1942 are replaced ,but that is for repairing them,not change them. Because we must ensure those files are the default install of BF1942, otherwise some problems maybe arise with the mod.
The "config.exe" is only a quick config program and that is useful for users who is not use
English. The installation information of BF1942 was stored in system registry,include language and cdkey,
,if you lose them when you reshipment system,the "config.exe"can help you repair them quickly.
Turning off your firewall is not necessary for the default firewall of winxp.but we hnow some other firewalls maybe prevent new programs from connecting to internent,and no prominent warnings for a newbie,so this is a well-meant remind,and if necessary you only need to turn off this kind of firewall when you activate the mod,not all the time you paly the mod.
So they have this as their instructions in how to activate the mod and one of their bugs.
Activate the mod
★ You will be asked to activate the mod when you run it for the first time .the free Activation Code is :B8AD69604787623B5F88AC470FA0
★ Some firewall maybe prevent new programs from connecting to the internet.If you can't activate CIF mod ,close the firewall and try it again.
★ If you still can't activate CIF mod after closing firewall,try it an hour later.This is due to network congestion.
Bugs and problems
Here are some problems we have known,that is only appear with a few users,and we will repair them in next update.
★ Some users click the mutiplay link in the main interface but a installation of MS Office appears, but you can cancel it
Very worrisome indeed.
