I am sorry to say but this time I can't help you out, there is no announcement, no notifications, no activity from the shit-load Playdium who is a national organizer for WCG pakistan, if you visit their site:
www.playdium.net and read the users comments in the forums then you will know they are one big POS..
furthermore, WCG itself is keeping their eyes close and taking no action against this situation in pakistan as WCG event deserve a exclusive promotion in pakistan!
I will visit the playdium tommorrow or later and will post here if I got any new information..but the chances are less.
you can also try posting here to get in touch with other players from pakistan who are interested in WCG 2007:
