Glad to here it started working again! I haven't been able to find out much yet as I've been extremely busy these past few days, but I would still like to attempt to find out what happened.
Regarding command-line options for WAW, I think that is more of a dedicated server thing or to do with executing the game (Something like this maybe: http://forums.firedaemon.com/493-call-duty-waw-how-run-service.html
?). I've only ever used console commands in WAW so not sure what else to say, sorry about that.
